Official Fit Assistance for Profile Design Bars
Quote | Reply
This is the place to ask for help if you are considering a bike that comes equipped with Profile Design aerobars, or are considering adding Profile Design bars to a frame or existing bike.

In no particular order, these are the brands that spec PD (off the top of my head)
Quintana Roo - full range
Canyon - Speedmax CF
BMC - Clipons on TM02, brackets/pads/ext on TM01 Flat bar (can't help with V-bar)
Scott Plasma 10
Ceepo
Argon18 E-117
Stevens Volt
Diamondback Andean
Cube Aerium C:68 Tri and TT
Parlee TTiR Disc
Wilier Turbine
Cervelo P3 and P2 (not P-series)
Sorry if I've missed any bikes

Obviously we already have assistance threads for QR, Canyon and Cervelo so you can ask there if you would rather focus on one brand.

If you would like assistance I need the following information:


Pad X is to the rear and Pad Y includes the cushion. Pad Z is the centre to centre width (or to the indents in the cushion if measuring an existing setup).
Grip Z isn't vital but is handy with some modern extensions and is the width at the base of the grip area (so that angling the grips in isn't part of the calculation)
Ext length is from the rear of the pad to the tip of the extension where the shifter inserts
Tilt is the inclination of the armrest (with the assumption that the extension will tilt too)
Add preferred grip angle and armrest if you like.

For background - I have been consulting to Profile Design for several years - first working on the Aeria Ultimate project to define the fit range. Then leading the development of the new generation brackets (Flyt series), Armrests (Ergo, Race, Boom) and Extensions (the ones with angles as names). I also founded Velogicfit (have now left) - developed 3D motion and aero capture software as well as the only bike finder that works with Pad XY.

Didn't want to clutter the top post, so here is the explanation of why each measurement is important

Some bikes based on classic find (assumes 0 deg tilt)


then we tilt to 8deg




And finally to 15 deg



You can see that stem lengths and spacer heights change to account for the pad moving back and down as it tilts.
I like to build bikes exactly right first time, so being able to accurately calculate how to hit the target position is crucial. Which is the genesis of these tools.

Appreciate this. I've been looking at your website over last few days trying to figure stuff out but am still no clearer on my options.. had been looking at p2 but there are deals on e117 frames at moment. Any options considered though..

Cheers

Pad X 460
Pad Y 655
Pad Z 215
Grip Z 85
Extension length 395 but could use a bit more
Tilt 8.5 deg

With the Sonic/Ergo bar


On the XL Argon you would be slammed. To the point that I'd suggest going with a Subsonic bar so that there is room to go lower in future.
For stability you would be better on that than the L
There are 8 rows on those pads - the search aims to be in the middle of the pad adjustment range so you've got room to tweak there
Of course, if you're in Australasia the XL is sold out in the clearance models and the current model shows as special order on the suppliers site.

The L would be OK for handling, just a bit less stable in the aerobars than the XL

Anything else of interest?

Dammit. I checked earlier in the week and there was stock in the XL Argon... Oh well.

Of those listed, probably only the Canyon or the lower range QR are also of interest.

I am looking at the Wilier Turbine and trying to find out what PD aerobars are used on top of the Wilier’s basebar. Can’t find any data on the pad width Adjustment range (only tilt/ pad X/Y tables are available on their site). I also see that Wilier is using alloy 35a extensions on this bike, is the rest of the bar carbon or alloy? The stem must be Aeria (like) because there is an option to attach the Aeria hydration to the front end. Would appreciate any additional info.

The Turbine has its own integrated carbon basebar/stem - Wilier designed the front part to match the HSF Aeria mount so you can use the bottle (and their testing shows that the bottle is definitely faster).
I didn't realise that the pad Z (width) hadn't made it into the published fit guide (I included it in the draft I wrote for them). Z options are the same as the Aeria Ultimate.
The Turbine still comes with Boom pads I think, so you would want to change to Ergo or Race unless you need a really wide position.
Ergo 124-253mm in 18.5mm steps
Race 142-235mm

If the alloy extensions bug you - go for the 35C+
Normal carbon extensions are only slightly lighter than alloy, C+ is half the weight.

Much thanks, very helpful.
So the parts above the basebar (tilt brackets, etc) are essentially Aeria hardware? I just wonder (based on the extensions choice in this otherwise expensive bike) how heavy the whole aerobar setup is vs. a top carbon aerobar like the Aeria or integrated alternatives I am also looking at (like the Argon 119).

Everything above the basebar is standard PD stuff yes. There is a lighter Aeria Ultimate bracket (the Race bracket) coming soon - partly at the request of Team Astana wanting to shave weight. The Race bracket is essentially the standard AU bracket with a smaller wing, so it doesn't have nearly as much adjustment range.
The Turbine bar would be much lighter than AU as it has an integrated carbon stem. I don't know about the Argon18 bar.
If weight matters to you then non-disc and not having specific bars are good places to start.

Thanks again, much appreciated. I am not weight obsessed, just wanted to make sure no corners have been cut in the aerobar design. Wilier is hardly a name in tri bikes, but this Turbine surprisingly checks many important points.

Wilier have come a long way in the last few years, the Turbine is a good bike.
Wilier got advice from bike fitters when developing the bike - which was to use the AU parts as they offer the best fit range. Plus it saves a lot of money in development for them as PD already has a wide range of options for extensions and armrests etc.
And it's the only superbike that has a fit guide that deals with tilting the bars :-)

I'm on a 2014 Cervelo P2 - 54". I'm swapping out my bars to a Canyon H30 basebar with Subsonic extensions. I'm hoping to know where to start with the set-up. I currently have a 110mm 1/seventeen stem on the aerobars now. I also have an older 90mm 6deg stem in the parts bin.

Pad X = 471 mm
Pad Y = 640 mm
Pad Z = 265 mm
Grip Z = 99 mm (grip center to center)
Extension Length = 353 mm

Very much appreciated.

This might be slightly off topic, But I’ve just received my Aeria Ultimate bars with the 35+c extensions. First of all, How short Can I Cut the extensions relative to the clamping area, flush or leave a bit?
And second, I like my extensions higher relative to the armrests, Can I turn them and cut to fit (if it fits, havent tried yet)?

Pad row 9 means all the way forward (but with the offset rearwards)
Pad Col 8 is the widest setting
I assumed a tilt of 7.5 deg as being able to do that is why you are changing bars.

You will need to set the brackets as wide as possible on the basebar to get the grip width, or acquire a 50a (or 4525) extension that offers a lateral offset to the grip. Setting the brackets wide also required to get closer to target pad width.
You're unlikely to be able to pair a Subsonic with an HSF Aeria.

1. you are supposed to have 10mm of extension sticking out the back of that bracket. Bolt clamps require more, but that's not relevant to you.
2. They haven't been tested in that configuration. They were tested a great deal in the standard setup as it's really not easy to make an extension that light. If you do want to get higher rise I'd suggest a 50a extension (has to be alloy if you still intend to use the aeroport) or look at the USE alloy extensions.

That the brackets are bigger close to the stem than the higher rise options. You may get away with it if using risers - I'll check with my team later on.

Hello,

First thanks for helping everyone with this since there isn't a fit calculator on the PD site.
I'm interested in moving to a deep mantis position with around 25 degrees of tilt. The best way to achieve that seems to be with clip on aerobar brackets. Also wondering if I can get a few cm lower without an undermount setup.
Currently using the tri rig alpha x with the omega x brake which has been an amazing bar, but can't go any lower without the undermount setup and doesn't tilt past 15 degrees or so.
Here are the numbers I would be looking to hit:

Frame is Cervelo P2 size 54, stack 522 reach 411

pad x: 510
pad y: about 585?
pad z: about 20 cm between the bolt holes I'm using. With my tri rig scoops, which I want to keep using, the z width between the cushion indents is about 17 cm
tilt: would like to try up to 25 degrees
ext length: not sure since my existing setup won't really get there. I would estimate maybe 38 cm from the rear of the scoop pad to the tip where I would want the extension to be. I would like to keep using my existing zipp evo 110 extensions anyways.

If I was to make the switch I would like to use the aeria ultimate stem and the hydration system.
I imagine I would also need something like the svet base bar and the subsonic brackets, but I'm open to anything.

Is it possible to get a combination of parts that will hit those pad stack and reach numbers?
how does cable routing work through some of the PD base bars? Can cables be routed internally through a base bar and out the back of that aeria ultimate stem? How about running cable straight down to the omega x front brake?
Can the extension bracket accept M5 or M6 bolts, which is what the tri rig scoops use?

Thanks!

Sorry for slow reply, it's a bit more involved than the normal calc.

I do need to clarify where you've measured the Pad X to?
If it's rear, the closest I can get is 498 with a stem to fit the HSF Aeria
If it's centre then it's less of a drama.

Cool thread.

Can you give me 660mm pad stack and 515mm pad reach to back of pad w/ 15* of tilt for Aeria Ultimate bar and stem? What would that backwards calculate to frame stack and reach? I'm in between two frame sizes.... QR PR5.

thanks,
Eric

As far as I can tell it takes ~20mm of spacers (incl hset cover) to match the height of the QR bento
But the 56 is nearly at max pad reach (11 out of 12 row options where 1 is most set back)
58.5 is a less extreme pad position (but gives the room to lengthen out)

The difference between pad row column and description is that description splits the high level view down to exact placement on the bracket

Thanks, I suspected as much. The client is in between sizes from both a fit and a bar choice perspective.

I was under the impression that Aeria Ultimate had pad and aero extension tilt capability, but I'm on the Profile Design site and that does not appear to be the case unless I'm missing it. There is plenty of lateral (left and right, fore and aft, and some toe-in), and a ton of vertical adjustment with many riser options, but I don't see angled shims to tilt. Is there a way to add any pad and extension tilt? -c

Angled shims are a bodge to fix aerobars that lack tilt (with a couple of exceptions where they are part of a cohesive design approach)


You can see on the AU bracket that it tilts on the curved mount (where the numbers are)

You have an Aeria 1, not an Aeria 2 (which the UItimate is).
If you have an Aeria 1 you can't use the Aeria 2 brackets, you would need to order an Evo bracket https://profile-design.com/...ucts/evo-bracket-kit
The Evo was designed specifically to add tilt to the older model bar - PD had sold many thousands of those so didn't want to leave users without a solution to add tilt and better adjustment range

New products shown at Eurobike (continuing from the thread about WS)
Everything aside from the brackets is new in this image


43ASC (aero shaped carbon) extensions with Race+ armrests on a Wing Ultimate basebar



The principle behind the extension was to sweep the extension body across and up to where the riders arm is. The idea being to make one body from the perspective of the wind. CFD analysis was promising and led to the fin that tucks into the inside of the wrist.
Obviously there are length constraints, so a shorter option will follow a few months after this one.

Race+ armrest is a 40mm longer version of the Race, with a new 5-10-5mm tapered pad and grooved surface (same as Ergo+) for traction and moisture wicking

Wing Ultimate addresses the weight penalty of the Aeria Ultimate stem by integrating the stem.

Do you have any idea how to get angle adjustment on a J5/Supersonic bracket with risers (I think 50mm). Rotating around basebar leads to other fit problems...

Also, how long will the ASC extensions be in the large version uncut?

Is the loss of reach a problem? Have you flipped the brackets forward prior to tilting? I have my supersonics in the forward orientation and tilted to 15deg. There isn't a product from PD to tilt the SS any other way.

Unfortunately, reach (and hitting my knees against elbows) are issues - I am rather tall, 204cm/6'8" with long limbs.

I have my current extensions maxed out, hence the question about the ASC length.

(I'm cross posting here and in the Official QR Fit thread)

I have a new QR PRFour with a Profile Design cockpit that feels too small. I have the seat set back and the extensions moved forward as far as possible. I also have the pads as far forward as possible. My most comfortable position has the tips of my elbows on the pads and my hands dangling over my mechanical 105 shifters (and even then I can only stay in the extensions for 4-5 mins at a time).

Should I try getting a longer stem? The bike has a 70mm PD stem; I'm thinking of getting an 80 or 90mm stem. Or do I need a different bike?

I'm afraid you need a frame two sizes larger (maybe even 3, would have to do a proper fit to know)
Shorter cranks would be nice too
You don't want to be in a situation where you are making yourself fit to the bike (which is what you've been trying to do) instead of making the bike fit you

Sorry about that.
If you need a solution for 5 weeks time, then sure - get a 40mm longer stem, it will feel a lot better. But it will make the bike feel less stable, whether or not that is a problem is individual - some people don't care and others do.
What info were you given from the fit?

Below is a data handout I was given for my fit. The QR PRFour data is in the far right column. My pads are further forward than noted in the handout, as I moved them to try and get more reach.

The other two columns are before and after fits on my Canyon Endurace road bike (incorrectly labeled as Canyon Ultimate). The Endurace (size S) I purchased years ago without being measured by a fitter and it turned out to be too small. I brought it to a fitter (different than the QR) who put on a longer stem. I still suspect the bike is too small (reach). Anyway, I mention it because I suspect the new fitter based my QR measurements/recommendation on my Canyon.

There is no reason why you couldn't try for example 100, 110, or 120 mm stem. If anything, I would guess that having that longer stem makes handling more stable, which isn't a bad thing especially in a tri/tt bike. Remember that 40 mm (more reach) is roughly equivalent to two frame sizes, so you have plenty of adjustability. That's the beauty of those non integrated cockpits...

(Fwiw I would try a 120 mm stem and if that's already too long, you'd anyway have the chance to move the armpads rearwards.)

You're confusing road handling, where a longer steering lever reduces the input required to make a manoeuvre
And tri handling, where putting more weight over the front wheel can make the bike feel unstable (again, rider dependent)
It's more likely on a small frame where there isn't much front centre to start with
The OP has compensated for not enough reach by moving the saddle back, so needs a lot more length in the cockpit - which could be addressed in the short term with a longer stem (and there is 7.5mm more reach on the armrests) but I wouldn't like to advise someone new to tri bikes to be finding a 140mm stem

I haven't had anyone your height prefer 165mm cranks or have better fit numbers (using motion capture) since I got a fit bike with adjustable cranks. I wrote on the topic in some detail here.

Your fitter sized the bike well with he information they had, the QR fitting document gives the coordinates shown (but their tool not graphical)

Your coordinates are middle of the reach range
The failing in this calculation is industry standard. No one calculates for the impact of tilt

Which pushes you right to the front of the reach range, just to hit the original target coordinates

So that explains part of the problem, the tools available to your fitter are inadequate

The other part of the problem is how you arrived at the position in the fit. This could be that the fitter didn't try stretching you out or you weren't able to provide useful feedback on different positions.

What you've done now is compensated for feeling cramped by shifting the saddle back to get more distance to the bars, but that cramped up up your hip, so you raised the bars to relieve that.

This is what happens if we add 40mm to your current pad x and keep pad y about the same as you've set it (not from fit data)

As mentioned - a 120mm stem would be a way to try out a longer position, but ideally a larger frame would be the nicer solution

I'm perfectly aware of those two factors, and sure it can be that nanban_ronin's weight distribution will be too far forward with a longer stem, but as said, needs to test and just see how he feels on it.

Actually, in addition to maneuvering and weight distribution, there's a third factor to how stable you are/feel on the bike. (A bit difficult to explain without a picture, so hope the following makes sense.) When the reach is too small, the center of rotation (i.e. where elbows contact the pads) of your body might be too far back and you feel like you are falling over the bike. Moving the center of rotation forward (e.g. with a longer stem) should improve stability from this perspective and in addition provide nice support towards which your elbows can lean if you have bit of tilt in the bars/pads.

Sure a bigger frame would be a more optimal solution but I don't see any reason why not to try a longer stem meanwhile. Costs maybe 20-30$ and should be in stock in any bike shop.

Thanks, cyclenutnz. That blog post was interesting, I wasn't aware of the advantage of smaller cranks. Although 140-150mm cranks sound shockingly short.

So that explains part of the problem, the tools available to your fitter are inadequate

The other part of the problem is how you arrived at the position in the fit. This could be that the fitter didn't try stretching you out or you weren't able to provide useful feedback on different positions.

My fitter's methodology was to first measure and fit me on my road bike, which I believe to be too small (I consulted no one when purchasing it). He then moved me to a fit bike and we carried over most of the same measurements. He also seemed to think I was really flexible and could hold an aggressive aero position (I can't touch my toes).

This is what happens if we add 40mm to your current pad x and keep pad y about the same as you've set it (not from fit data)

As mentioned - a 120mm stem would be a way to try out a longer position, but ideally a larger frame would be the nicer solution

I can't say I fully understand how these data and graphs work, but I do see a size 50 with a 120mm stem still has me at the edge of the dot grid and utilizes a lot of spacers.

Road bike fit and flexibility don't have a lot to do with fit on a TT bike.

Hi Cyclenut,

I have a shiv tri disc and it’s a bit of a punish to angle the extensions but I have found a couple companies that make an angled spacer for the central stack.

Keen to understand the height rise on those snazzy new ASC43 extensions and the degree of tilt most people would go with if they’re looking for a higher hands position.

The angled spacers I’ve found come in 10, 15 or 20 degree options.

I’ve previously used a tririg bar with 115mm height rise and a 7 degree spacer under arm rests. That was comfortable but height rise from pads to top of extensions ends up being around 100mm and I figure I could go higher.

Hi Cookies

The rise on the 43ASC is intended to pair with a long armrest in full contact with the arm, it's not really going to work if you like to put your elbow on the pad and raise your hands up. You can see on the diagram I posted earlier in the thread that the rise is ~90mm (measured to centres)
Usually I find riders achieve good comfort and bracing with a 10-15deg angle.



That's a quick sketch of an armrest tilted 7deg with a 115mm rise extension for a fairly average length setup
You can see the equivalent rise if the extension had tilted with the pad would be 74mm
So if you can tilt the whole mono on your bike the 43ASC will give you ~16mm more rise than this example

Hi Cyclenutnz, what size QR PRFour and stem would work better than my size 50 with a 120mm? I think you used a size 54 and 80mm stem in your analysis. I'm working towards exchanging my bike. Thanks!

Any chance the wing ultimate basebar will have a long stem version? I really like integrated stems, but they always seem to be short (90-100mm measuring to the center of the pad bolts)

I'm afraid not. The fit window for that bar is middle of the range. The solution for extremes is the Wing20C+
Or wait a few years for the next generation bars and bikes

Sorry it took a while to get back to you.
I am on an old Cervelo P3C (2009) in size 61. Frame stack&reach is 564 / 454. My pad stack&reach is 648 / 553. I have played around with stems before.
It can be a bit tricky to get from top of headset to my pad position, but the really difficult bit is actually maximizing the distance between pads and end of extensions.

Sorry for the slow reply - I'd go up to the 54 as shown in the chart, I think your position will end up higher and longer than currently.
Obviously going to a fitter first didn't work out for you, which is unfortunate as you did everything right.
If you don't feel confident trying with a fitter again - you can post a fit critique request on the forum and get some useful feedback (I don't take part in those as I feel hamstrung without my 3D motion capture data)

No problem, I appreciate you getting back to me. I contacted QR and they are willing to swap my size 50 frame for a 54, so hopefully it works out. I spoke to my fitter; he stands by his recommendation and noted that I don't have a lot of seatpost sticking out on the size 50.

As for seatpost extension, from your video I get this


Which means your saddle needs to go up, if you then get 155mm cranks that's another 10mm. So the seatpost extension will be similar on the 54 to what you have now.
Most importantly - the bigger frame will give you the reach that you really need

Any update on availability of the PD 43ASC extensions?

I asked the following on the PD Oceania Facebook site, but was told the info will be released soon...

Is there anymore details on the configuration, i.e. are the risers integrated into that base bar or is it more modular like the standard PD brackets that wrap around a 31.8mm centre clamp?
Does the new base bar connect to a standard stem?
Any BTA bottle cages / computer mounts coming for this?

Anyone got anymore info?

The 43ASC is just the extension, with a standard 22.2mm clamp area that is 110mm long

Availability - the APAC manager has endeavoured to get a small number into Oceania. There may be a very limited amount available in Australia in the next few weeks. I'd suggest finding a PD stockist and getting them on the case with the distributor (bikecorp) as the extensions will likely disappear in a day or two based on the number of queries I've had.



The Wing20C+ bar uses the aeria 2 bracket system, that has specific risers. It also has a 20mm change in grip and pad stack by flipping the bar.


The Wing20C+ works with any 31.8 stem, but is intended to pair best with the Tri Stem that I've mentioned earlier.

BTA mount specific to these extensions will be a while away (as in, hasn't started anywhere other than in my head)
Computer mount is nearing the end of the design phase, production these days probably means another year to be in market. It's quite nifty as I will finally get the garmin mount I've always wanted.

Thanks for the info! Are the risers for the Wing20C+ the same as the Aeria 2, i.e. do I need to buy new brackets if I invest in the new bar?

The hydration bottle in the picture ... any details on that? How is it fastened? Does it require the Tri Stem or can it connect to anything? (I have a BMC TM01 with a proprietary 'P2P' stem)

Thanks again

The risers have changed, but it's all forward and backward compatible.
Aeria 2 uses A2 risers, which have built in curves
A3 risers were revised to be lighter and cheaper (but cost increases have wiped that) and you can see in the image above they're flat top and bottom then have an adaptor sitting on top for the bracket.

All you need to do to use A2 risers is sit them above the adaptor. A3 under, A2 over is all you need to know

The bottle pictured is the HSF Aeroflow 700 (there will be a 900 and 1050, referring to the volume in ml)
It uses the same clip system as the HSF Aeria
I'm afraid there is no way to attach the clip to any of the generations of the TM01, including the upcoming Speedmachine

When the previous Aeria bottle was released, you suggested it tested very fast, making most bikes faster with it attached. Eyeball sind tunnel agreed with that. It was very slim and nicely shaped. How does this new chunky bottle compare?

The HSF Aeroflow isn't replacing the HSF Aeria. The aim for the Aeroflow is to work well with 31.8 bars - the hammerhead hides the 31.8 and the aerobar clamps. My goal is to make mortal bikes more super. As mentioned, production cost rises have blown out the original price targets, but still - a Tri Stem + Aeroflow is cheaper than an AU Stem + HSF Aeria.

As a more price oriented product the R&D that can go in is a bit limited. So what I did was measure the headtubes from the QR PR Series and Cervelo P-Series, then get my guys to make the shape of the bottle flow nicely. Those bikes chosen because they are the extremes of head tube depth on modern bikes and also are likely to be the most common models to have the bottle fitted.


Red looking at Cervelo, blue for QR.
The intent being to make the two parts look like one airfoil to the wind. Yes there is a gap as we don't have the rubber gusset of the HSF Aeria but in theory the flow should reattach

Then we did basic CFD to check what was happening at the bars
no bottle


with bottle


reduction in higher pressure areas by taking away faces that are presented to the wind

Won't know how well this has all worked until we get some testing done. But the principles behind the design are quite strong

From a functional viewpoint - being able to offer multiple sizes by simplifying (compared to HSF Aeria) the mould requirements then means that riders can choose the size that covers more of their head tube on larger frames. And for larger frames can carry a lot more fluid than previously possible. For small frames - the HSF Aeroflow 700 fits onto bikes that can't use the HSF Aeria.

Hi -


I've had a bike fit done and picked up a CF 8 Disc in size small. I've got longer legs and shorter torso, and currently have terrible flexibility that I'm working to address, so reach was a bit compromised. While I work on flexibility, what are my options for armrests that will allow mounting a little rearward on the PD Subsonic brackets? I was looking at things like the Ergo+ / Race+ armrests mounted in reverse, but noticed that was specifically frowned upon in the associated manual.


Any other feedback on things to consider?






Thanks,
Bryan

PS> I've cross-posted in the Canyon fit thread, but the armrest question might be better addressed here. Hope that's okay!

Not the current TM01, but the older one with the Tri-Angle stem used a standard 31.8mm bar so that would work as long as the bar had a wide enough central area.

New products shown at Eurobike (continuing from the thread about WS)
Everything aside from the brackets is new in this image


43ASC (aero shaped carbon) extensions with Race+ armrests on a Wing Ultimate basebar



The principle behind the extension was to sweep the extension body across and up to where the riders arm is. The idea being to make one body from the perspective of the wind. CFD analysis was promising and led to the fin that tucks into the inside of the wrist.
Obviously there are length constraints, so a shorter option will follow a few months after this one.

Race+ armrest is a 40mm longer version of the Race, with a new 5-10-5mm tapered pad and grooved surface (same as Ergo+) for traction and moisture wicking

Wing Ultimate addresses the weight penalty of the Aeria Ultimate stem by integrating the stem.

Does anyone have any update on availability in Europe please? I need new extensions and would love to buy these but it seems nowhere to be found yet...

Sorry for the slow reply, we took a longish summer holiday

There aren't any armrests you can mount further back than the Ergo models that came on your bike.

I do have to ask how your fit was performed, because your measurements say TCR, which implies you're setting up your tri bike based on a road bike fit.
In which case you could look at moving your saddle forward, which would open your hip angle and increase your pad x

Hello and thanks in advance for the assistance! I just got an X-PR (size 54, 90mm stem, 160 crank) with PD ultimate aeria wing/ergo 35c extensions, and am a little confused on how to get the max advertised armpad width. How do I orient all the bolt holes to get the 254mm Pad Z? Any other tips/recommendations for fit would be great. Thanks!


Pad X: 424 (470 to saddle)
Pad Y: 695 (fit report says to top of armpad which I assume means where my arm rests rather than the highest point of the cup!)
Pad Z: 253
Grip Z: 71
Ext Length: 357
Tilt: zero

Hi David

Tangentially related to Profile Design, but looking at adding a Aeria Ultimate to my P-Series.

Question about stems, the 1/Seventeen Stem HSF Aeria Faceplate says it's for the 1/Seventeen Stem (not the 1/Seven) but I don't need a -17 stem drop, would I be able to use the 1/ZeroSeven instead or am I stuck wit the 1/Seventeen?

Thanks

Re: Official Fit Assistance for Profile Design Bars [gromaton] [ In reply to ]

The 1/zeroseven doesn't work with the HSF faceplate because it would tilt the bottle up, so we haven't safety tested (just in case you were thinking you could deal with the tilted bottle)

For a 100mm stem on a P-Series there is a 14mm difference in Bar Y between a -17deg and -7deg stem (unless you have a 48, then it's 15mm)
Which should be possible to make up with aerobar risers

One final question, the Aeria 2 is it worth waiting for that to hit the market and go for that? Or just get the Aeria?
And would the faceplate be backwards compatible?

Target race will be 70.3 Taupo in December and happy just using my zip tied bottle cage BTA for training till then.

Thanks

As you can see - wider side of the pads to the outside, bolts on the most outside bracket holes

Your pad Y will be to the back or middle of the armrest, including the height of the pad

For your position

You are at the highest stack and most setback point

Are you asking about a new bottle or bar? Assuming bottle:
The HSF Aeroflow is coming and is focused on disc brake bikes, goes nicely with a P-series.
If you have a large frame the HSF Aeroflow will give you more fluid capacity than the HSF Aeria
The HSF Aeroflow and Tri stem were designed together to optimise spacing to the headtube
The HSF Aeria and 1/seventeen stem sit further forward, so with a disc bike the best option is the HSF Aeroflow
I don't know ETA for consumer products, I think they will be available well in advance of Taupo 70.3

I ordered what seems to be the last pair of 43ASC from PD in the initial batch to the USA, and am excited to try them out. I built a QR V-PR last summer, which I originally built with the Metron TFE Pro bars (305mm size), but I could not find comfort on them. I think the issue was my forearm length (I'm 6'2" / 188 cm) and how much elbow I had hanging off the back of the pad. I switched over to the TFA cockpit, and after some fitting iteration, found comfort.

Now, on the indoor trainer as my experience and fit progresses, I'm finding myself wishing for a more vertical hand position (bit of wrist discomfort on long rides). Hopefully the solution will be in the 43ASC. A bit more free aero would be an added bonus.

Cervelo P3 54cm with 100 mm 6 degree stem and 3T Vola Team Aerobar, looking to add stem-attached hydration since I've angled up my extensions which tilts my BTA bracket (I have used wedges to re-level the bottle but I'm not wild about that). I'm thinking Aeria on 1/seventeen stem/faceplate. I have Tririg Omega One brake on the front. What stem length would work to allow room for the brake and neatly fit the Aeria side flaps to the headtube? I think I could use a longer stem if anything so I don't want to go shorter than the existing 100. As you said the new HSF Aeroflow is designed more for disc brake I assume the Aeria would work better for me than waiting for the new design?

You could wait a couple of months for the 105mm Tri Stem (production has arrived at Taiwan office, now needs to ship out to distributors)


But the Vola doesn't do full internal routing for the brake cables so not really much point

So yes, a 1/seventeen in 100mm or 110mm would be the go.
To match your pad Y you will need to make up 16mm of stack under the stem or as aerobar risers
HSF Aeria definitely the better choice for your bike

This is the HSF Aeria with a tririg caliper (left the front cover off) on a medium Speed Concept 7.0, which had a 13mm shorter headtube than the P3 MKII (4mm shorter than P3 MKI). The 1/seventeen then sits ~14mm higher than the AU stem so you would expect the shroud to be 20-30mm above the bottom of the headtube on a P3, if you have the stem slammed

There is a 52ASC in development now, but that's going to be a year to market, so not much help if the 43ASC doesn't work for you
The aim being to provide a really relaxed wrist position with all of the cool features of the ASC design.
There won't be any lower angle grips (before anyone asks), just the 43 and 52 on the roadmap.

I've got my 43ASC installed and tweaked around on my bike fit a bit. In total, only about 3 hours of ride time on the trainer to date, but so far I like them quite a bit.

A few comments on these extensions:
- I wear a watch, and don't find the inside fin really bothers my watch arm much, but I do wear my watch up my arm a bit (~15 mm above the head of the ulna).

- I think a bit of thin padding over the wrist bend area, and maybe along the forearm contact area would help. I've got some 3 mm padding on order to play with

- I wish the hand grips were longer. My hands are pretty big, and I can only get about 3 1/2 fingers on them or less. I still need to move my SRAM Clic bar end buttons over, and hopefully won't have an issue pressing them. There's no way I could make wireless Blips work on the end, as in Slowman's article on the 43ASC bars. It would be awesome if Profile Design would ship the bars with longer grip sections, maybe with cutting marks, and allow the end user to cut them to length.

Thanks for the feedback
For padding - we considered making something, but figured that the aerobar tape provides an option for that

For the grips, like most PD products - sized on the basis that I am at the top end of cyclist/triathlete dimensions


Fits exactly with Di2 buttons
SRAM clics didn't exist when the project was started, just the blipgrip. Grip is definitely too short for clics for most people.
What I'd suggest for AXS is remote blips with a holder


That way you get more length than clics.

As mentioned - future models will get longer grips

Your 2nd picture is exactly how my hands/fingers look on the grips. I think I will design up some short extensions, 3D print them from PETG, and glue them in to get my bar end Clics up to an equivalent Di2 height.

Thanks for sparking the idea.

I just got a set of the 43 ASC aerobars. They are very comfortable and fit well. The only issue is, because they are not round, I don't have a way to mount my cycling computer anymore.

What do people recommend for mounting a cycling computer to non-round aerobars?

I will answer my own question for others that may have the same question. I used the 76 project mount. It works great. It looks like it would get in the way of your hands, but they wrap around the mount quite comfortably.

Hello Cyclenutz.
I have a 1 inch steerer on my 2011 Felt B12. Is it possible/ advisable to shim up the steerer tube from 1 inch to fit the 1 1/8 inch stem of the Tri Stem? would it be smarter to go with another Profile offering and get the HSF faceplate?
Thank you!

If you don't have a bar with a centre hole to allow routing the brake cables into the stem there isn't much point to the tri stem. You would be better to save some money with the 1/Seventeen and HSF faceplate.

I've had no issues shimming 1" steerers to 1.125" stems

Eventually* there will be an alloy wing basebar that will have the internal brake routing, if you did want to get a tri stem with a view to tidying cables in the long term.

Hi, just a quick sanity check on compatibility.

I'm running Profile Aeria Ultimate 2 bars with the Aeria Hydration system. I'm thinking about fitting the 43ASC extensions, apparently there are a few coming back into the UK soon.
Note there are no spacers on my extensions currently only the pole holders and angle.

Will the Aeria Hydration and the 43ASC extensions work ok??

I've been riding on the 43 ASC for almost 3 months now, and I really like them. I do not notice any interference with a watch on my left wrist, for what it's worth. I initially thought I would want to add forearm padding to the extensions, and bought a few different hardness levels of padding to test. I never got that far however; as soon as I started riding outside I felt no need to add any padding.

The largest issues for me were needing to extend the cables on my SRAM Clics (Blipbox is mounted in a bento box on my top tube - this issue exists for all aero extensions unless you put the Blipbox on your base bars), and needing to make the hand hold part of the bars longer to deal with my large hands. Here is how I handled the latter.

I didn't want to modify the extensions until I was sure how much longer I needed. So, I designed and 3D printed a bunch of bar end dummy Clics in 5 mm increments. I rode indoors with these until I found the best comfort:





Once I was settled on the size I need, I machined a pair of extension pieces out of Delrin






Then I trimmed the extensions with my carbon steerer tube trimming clamp and glued in the Delrin pieces with urethane 2-part adhesive






Thanks,
-Steve

I’m curious if the 43 ASC extensions fit with the clamps that come stock on the rim brake version of the Canyon Speedmax. I believe they are the subsonic brackets. I worry that I will have to trim the 43 extensions too far to fit that they will not fit if I go to an opened ended bracket in the future.

Would only work on the Subsonic if you have super long extensions, really a very rare scenario and not worth it.

I just got my 43 asc’s. very nice. maybe i am too lean, but for me they do not contact my forarm at all really. My hot take is that maybe if my forarms were a couple of inches longer (pads further back) i would have better contact. the forarm section seems to be designed to work with pads that are flush with the top of the extension bars clamping area.

note: right now i am using the felt dagger stem/pd svete bar/bayonet mounts/brackets, and the original profile design race armrests (5mm pads i believe).

The 43 asc’s have a shorter clamping range, so to get them as short as i want, i need a combined base-bar/extension clamp solution (supersonic). i may upgrade to the race+pads while i am at it.

the ergonomics of the bars make me think they were designed for someone with narrow hands, long forarms, or a very very low pad setup. or they were never designed to support once you get below the wrist.

"or they were never designed to support once you get below the wrist."

It would have to be a very different design to offer a reasonable range of adjustment and fit a 22.2mm bracket.
Always intended as an intermediate step between full round and one piece.
Also, if you get a race+ armrest it's 40mm longer so you have a good contact area at elbow, then the ASC design adds wrist contact.

yeah i measured it out and they are obviously designed to work together. also tempting to make a foam contact point in between for fun.

- clip plastic cover on, top of fill port covers should be flush

Why does PD not sell a complete aerobar with the new 43ASC? I'm not going to buy an aerobar that I will immediately "throw away" the extensions for.

Alternatively, why can I not buy a base bar with flat mount risers, vs the standard round bracket clamp.

The Wing20C+ is about to be available with just brackets, flatmount risers are available separately


It has been a long road to get this to happen as there has been a historical preference for selling complete bars. But I have way too many take off carbon extensions from that policy.

A future step is that all components will be available individually from key dealers, so you can choose the brackets too.

43ASC not sold in a complete because of the fit limitations it brings. So the solution above is aimed at reducing wastage and cost.

Sorry for the slow reply on this


So ~126mm from bar centre to the tip (max insert ~85mm)
Then 230mm min for 43ASC-340
+ whatever offset you have, minimum is 17.5mm if you're slammed forward
Thus the shortest pad-ext possible is ~374mm

As for garmin mounts. Working on something but it's a while away as the first design got ditched.

I'm afraid not. My original aim had been to have the same mould for the standard and the plus, so that there could be a range of widths in both.
But that didn't work, so the costs for the plus were too high to make more sizes.
It is something I have in mind though, I always aim for a range of sizes

You really would have to test. The 880 is in the range for people that like the style of the aerodrink system. To hit the pricepoint there was no aero work done during development (in fact I was barely involved).
From testing other systems I'd expect a BTA to perform better, but you might be lucky.

That's the wrong bracket in the images on the site - it should be the standard bracket that has a larger armrest mount area. The race bracket has a lot more adjustment.
But aside from that detail - it's good to see a results for my efforts to give riders more options for dialling in their fit without having to buy extra parts.

This is the Wing20C+ sold as just basebar and bracket, allowing the rider to choose their extensions and armrests.
So instead of spending USD 725 to get the complete and having parts that may not be ideal, you can choose the bare option and get exactly what you want
Both options shown here https://profile-design.com/...ions/carbon-aerobars

For a P-series - the Wing20C+ with a Tri stem does a good job of tidying things up. Allows routing the cables through the stem to get a really clean look.

Hey Cyclenutz. I’ve been looking at finally upgrading the cockpit of my P3 and am interested in the Wing 20C+. However, I’m scratching my head trying to understand the pricing on this. The basebar alone is $290 and the bracket kit is $149 if I were to buy the parts separately. Yet on the website, the Wing with aerobar kit together is $556 - a difference of more than $100. Am I missing something? Thanks for your response.

The Wing20C has a 31.8mm clamping area for clip on aerobars
The Wing20C+ gets mounts for the integrated brackets (the + means added cost ;-) )
Slowman has given his thoughts on the differences here https://www.slowtwitch.com/...ursuit_Bar_8572.html

The main advantages of the + are:
- you can hide Di2 cables better (if you have them)
- pads don't swing back as much when tilted
- there are a bunch of addons coming for the A3 riser platform that can't be added for clipons
- looks better

Hi @cyclenutnz,

May I please request a similar fit range detail comparing the size 54 and 56 Cervelo P-Series?

I'm currently using an Aeria Ultimate II bar, 100mm Aeria Ultimate V2 stem, 35C+ extensions and Race+ armrests. I absolutely love this setup, but looking to switch to a disc brake TT bike this year and want to keep my cockpit - hence the P-Series.

My pad reach is 445 (back of pad), and stack is 635, I'm using all 15 degrees of tilt. Looking at the Cervelo website I appear to be between a 54 and 56?

I would like to go a little longer with the next bike - as I'm maxed out reach wise on my current bike. Some images using a basic fit tool to see just how cramped I may be with the current frame, pictured with 170mm cranks - 165mm cranks in the mail:

you're definitely a 56

Sorry I missed this question.
The only cable exit is out the rear of the extensions on any current model Profile Design extension.
So you would need to go over the top of the extension socket from the rear and down through the central hole

No you wouldn't be able to use the HSF faceplate on the Dagger stem, it hasn't been tested.
As to whether the tri stem would work - I don't have a contact at Felt anymore to ask. If the cover is size specific and you have a large size - maybe. But looking at the above image I think it would be unlikely as the bottle would probably contact the top of the fork.

The Wing20C+ would work well with the Dagger stem - allowing cables to route through the bar into the stem. With ASC extensions you can achieve a very tidy and comfortable setup.
For hydration you probably need to look at a BTA, there will be one suited to the ASC available later in the year.

Any tips for the best Garmin mount to fit Asc 43 extensions. So far the project76 (https://76projects.com/...t-computer-mount-3-0) looks best. I like the mount up nearer hands.

I think most people find the Project 76 works well enough
I just have a metal bridge zip tied across, because there is a specific one coming from PD in a few months

Can you share a picture of the bridge you are using for the asc bars?

Just got news that the 43/52 ASC are back in stock.

I just had a Felt devox adjustable bridge in my parts bin

So it's not a high class solution.
No picture as my bike and I are in different countries (this is a problem for fitness too)

The stock won't last long. Production can't keep up with demand so most distributors only get small amounts.

I was experiencing how elmuch time is needed with new tilt blocks from wattshop. Absolutely brilliant design!

What's your stack height you threw in the stock bayonet bridge?

As it sits with no risers center of pole is 50mm.
Not sure where stick the bridge because of difference in size of wattshop and felt riser blocks.

As this is a Profile Design focussed thread I have to point out that there are no 3rd party providers that are endorsed for use on PD bars currently. In fact there are several that PD would really prefer to not see used. Obviously you've got Felt bars so that's not relevant to you. It's just worth pointing out that only one other aerobar brand passes PD testing standards.

I just have the bridge for mounting my garmin up near my hands. If I needed a bridge I'd use the A3C integrated one as it's half the weight of the alloy and looks cool, but that's no good to you.

Thanks for the update.
Are you suggesting that the 53 ASCs ordered direct from PD should not be used with wattshop clamps with the inline pole clamp?

This toothpaste may be hard to put back in the tube.

The PD extensions are fine, they are tested far beyond ISO standards. As long as the clamp you use is within tolerance and clamps evenly you should be fine.

My comment was more directed at adaptors on basebars. And as a general comment, not specifically about what you've got. It's just that some aftermarket parts cause concerns for bar makers (including bike brands that make their own bars).

I'm a little concerned with that as well. See previous pic with adopter having a lip or overhang off the felt basebar.

I think the "evenly" portion of the build can be accomplished quite nicely with 52's.



Worst case I throw stock bayonet wide Bridget back on with the 52's with thr new race+ pads and call it day. "

Prob should have done the full PD cockpit threw on the 110 Felt stem and started fresh. Live and learn 🙏👍

I am planning to order PD ASC 43 extensions for my Cervelo P5d - how do I determine which length I need? Than you,

Measure from the front of the bracket clamp to the end of the extension (assuming you're happy with current position).
If more than 290mm get the 400 long extension.
If less than 290mm get the 340 version.
If less than 230mm I'm afraid the ASC series won't suit.

For the grip angle.
If you have SRAM AXS, get the 52 as the grip is longer to accommodate the low profile of wired blips.
I don't recall the angle of the ex11 grips and I can't check right now, but in general the 52 is more relaxed at the wrist and the 43 forces a tighter hand position.

Thank you. I should have provided more information. I am going to (finally) switch from the EX11 front end to the EX10 so I can tilt the bars a bit. I measure 300mm from the front of the pads to the tips of the extensions (400mm from the rear). Current extensions have 30 degree bends at the end, and that is just fine. Yes, I have AXS. Also to consider is mounting the BTA and Garmin both of which are very clean presently. I do NOT have technical expertise (or much ability) so PLEASE feel free to give me advice, changes, alternatives, etc.

You may be able to use the EX10 BTA mount

that piece on the bottom right goes on the extensions
But you may struggle to move it far enough forward to get 64mm from the other hole in the centre of the bridge. Hard to say without assembling to test.
Actually, your measurement is different from what I meant so you should have no issue. I'll take a pic later on to demonstrate then post again.

There is no nice garmin mount at this point, but it is coming in a few months (sits up near the wrists)

With AXS you will probably be better to go with the 52ASC, just to get the grip length
