Canyon usa were sent one this week. Will ask if they can take a pic on the cf sl.

why not just get the SLX?

Indeed, I'll be receiving the Aeria Ultimate to confirm just that. Will update here as soon as I fit it, as I agree, it would be a nice piece to add to a CF and help get it *close* to the form and function of an SLX.... at a significantly lower price, at a less aggressive geometry, with greater ease of travel. Certainly a fair bit of variance between the CF and the SLX....but the Aeria setup (we hope) will bring it dang close to the SLX.

It serves as a bearing cap, so it's not removeable. However, (and I can confirm this tomorrow when I'm in office and can look at the bike we have in our office) I believe we have a version that allows the stem to come down flush with the top of the headtube. I think we have a few of these in stock, and are in the process of getting these ordered (along with a lot of other smaller/fit-related parts). So yes, you can get the stem slammed. You can always call our in-house sales team, confirm it and order if we've got it in stock.

About $4,000.

Thank you for all the info Jay! I have a couple follow up questions.

First, if you do have any of these in stock (with the stem slammed) can you send me a photo? I'll message you my e-mail if so. Or feel free to post it on this thread. I'm sure many others would be interested to see it.

Second, if we did slam the stem, is there another energy box that would sit lower to stay flush with the stem? I heard there was another shorter box available, but I've never been able to find it on the website.

Thanks again Jay! This has been really helpful!

thanks Jay

“You are experiencing the criminal coverup of a foreign backed fascist hostile takeover of a mafia shakedown of an authoritarian religious slow motion coup. Persuade people to vote for Democracy.”

Thanks Jay. I'd be interested to hear about this as well. I have a CF 8.0 Di2 and the spacer can physically be removed. I didn't realize it was more than a spacer. I'm considering upgrading my cockpit to something cleaner, so interested to hear whether or not it's viable.

I grabbed the CF we have here in office and pulled it apart to confirm (and called the designer on the Speedmax, Wolfgang Kohl this morning, to confirm).... and it's different. In a good way.

The shape-integrated plastic spacer that sits under the stem is "just" a spacer. You can indeed remove it and drop the stem down to the compression ring that sits atop the bearing on the top of the headtube. The base of the stem is recessed such that it will sit atop the compression ring and act as a nice snug cap atop the compression ring.

With the excess steerer above the stem, things are a bit different. You can cut the steerer and run it flush. We do make a shorter bento box that will allow it to run in line with the stem... but don't have them in stock yet.

However, if you wish to leave the length of steerer uncut for any reason, the stem by its design has two "wings" at the top aft of the stem. You can make it simple by cutting the steerer flush. If you wish to keep the steerer intact, things are a bit different; the wings (as well as a very small amount of stem diameter clearance around the steerer) precludes you from using standard spacer bearings.

Finally, being 1 1/8" standard, you can carve the whole front end off and run whatever you want; a Zipp one-piece, your own stem, bar combo from ENVE, or... that Aeria Ultimate. I just received a test unit from Profile Design and quickly tossed it onto our CF 7.0 in office. it works a charm. The plastic spacer (if you mount it under the stem) will still be a bit of an issue, but a Dremel (or an old steel file) to take out an alignment rib will remedy that instantly. But it looks great.. and will look even cleaner with cables properly routed through the stem. And it's rock-solid, too.

Following here with a couple photos; a detail shot of the Aeria Ultimate stem and HSF bottle installed on our Speedmax CF, with a shot of the CF and the SLX side-by-side. I'm incredibly impressed. It effectively takes a Speedmax CF and morphs it quite quickly into an SLX in form and function and utility. It's not a mistake that the bottles look the same; anyone that has a Speedmax SLX will see the Profile Design marking on the bottle there, too.

And for future reference, I'll soon be opening a Speedmax Owners Thread, to answer any questions y'all have. Stay tuned for that.

The SLX on the left is a medium. The CF on the right is a large. And FWIW, the Profile Design Aeria stem is sitting atop a 40mm spacer, so the cockpit (and bottle) can come down that much further.

Hi,

which length has the stem? is it the 70mm or 100mm version in this picture? I want buy that system, but I'm not sure about the stem for my Speedmax size "S".

Daniel

The stem in the shot is the 100mm version.

Hi Jay,
can you share more pictures?

It's just remove the Canyon stem and switch to this one or you need to do some magic?

I've a Speedmax CF 8.0 XS from 2018 and I want to mount this kit.

Thanks!

Any idea how much does the v21 canyon stem weights? Need to change my 80mm to something longer and was thinking about PD Aeria. But it's mentioned to be heavy so I'm wondering how does it compare to canyon.

CanyonJay: that would be interesting to post a weight of a Canyon 90mm stem. Could you do it for us, pls? That PD Aeria Utimate stem in 100mm version weighs a hefty 455g acc. to the website. Thanks

Hey Jay,

What I didn't get ... is it necessary to remove the spacer or can I just change the stems and it will fit as well? They seem the same height and the aeria ultimate falls out deeper. Besides the shorter bento box still isn't available.

70mm stem: 214g = 168g (body including 2 screws) + 33g (front with 4 screws) + 13 (head plug with screw)
90mm stem: 238g = 192g (body including 2 screws) + 33g (front with 4 screws) + 13 (head plug with screw)

Regarding the low bento/nutrition box for the regular CF
Via local (Netherlands) Canyon support I (think/hope I) ordered the low version of the nutrition box; apparently you need two parts, the rubber outside and a plastic internal box.

One of these parts is labeled: CAYN Storage Shell E431-16
other one I don't know (I don't see the item-nr in my order status, just that there is an item)
combined price is around €15

Items are not in the webshop, so I would advise to call your local support team.

I have the ultimate stem on my CF 8.0 Di2 (medium). I also have it paired with the aeria hydration system. Will post pics soon

Excellent, thanks !!!!

I am having this stem put onto my Ceepo Katana. Was interested in they hydration system. Would love to hear your thoughts on it.

Off topic, but why isn't the 8.0 available in the U.S. along with the 8.0 SL? I can't be alone in loving the Canyon but not needing another set of race wheels. Drop the $1000 off the 8.0 SL price and remove the race wheels like you do on the European versions and you'd probably already have my money.

I'd love to see them! Did you just change the stem or did you have to remove the spacer as well?

Hi,

does anyone know how much steerer tube is protruding /of its original length with Canyon stem and a spacer/ after your install PD AU stem? Or you just put a PD top cap and tighten it down?

CanyonJay - you mentioned some "intervention" with a file/Dremel to file the spacer...What exactly did you mean? Photos pls. !!


Many thanks.

I dont have PD stem, just the regular Canyon but removed the spacer in this is how it looks. Bare in mind, that if you don't cut the steerer you have to use other spacers so the top cup will actually hold something.

Do you think that it would be possible to adapt the PROFIL DESIGN Aeria hydration at the original Canyon stem of the CF Speedmax (with Dremel !) or impossible because the stem profiles are really different.
Thank

Or another model or brand but lighter than the Aeria from PROFIL DESIGN

Not possible - the mounting system for the hydration requires the stem to be specifically designed for it

I disagree. It's possible. A German pro had it attached to her TriRig Alpha X. Today in Cozumel I saw another pro with it attached to a different stem as well.

Also, a profile design rep on ST said they are working on a much lighter stem that may arrive this summer

You realize the guy who said it isn't possible is the profile design engineer on slowtwitch right?

In fairness, anything is possible if you have a drill or skill with carbon.
So my statement should have been 'not possible with any standard parts'

Oops I did not! I'm an idiot, sorry.

But my statement stands. He said they have a lighter stem coming so I would either wait or get the heavy one for now and then swap.

I haven't seen how it was done on the Alpha X. The bike I saw this weekend looked like it might have used double sided tape or something. It was attached at the top of the stem only because the stem was much thinner. It's doable with some DIY

I do not understand how it is possible to propose such a heavyI'm always looking for a way to install a I'm always looking for a way to install a hydration system on my Speedmax CF
I ve found this :
https://www.youtube.com/watch?v=-pRb0IF5_1A

I still don't quite understand what is necessary to install the Aeria Ultimate stem and bottle.
Maybe you or someone else can clarify for me.

Do you need to remove the 25mm spacer under the stem in order to install the hydration system? If so do you need to cut the steerer in this case?

Thanks!

You only need the Aeria stem AND bottle, together. The stem has a c-channel receiver bolted into the base of the stem. it's here that you slide the bottle in and affix it. There's no way to retrofit it to any other stem; the two go hand-in-hand.

So you don't need to remove the spacers in any way. The Profile Design website shows the two units, but there's not really any visual as to how the two interface. You simply replace a stock stem with the Profile stem, slide the bottle onto the bottom of it until it clicks into place (it's easy to remove with the release tab) and that's it. Super easy.

Cool, thanks!

The Aeria Ultimate Stem V2 on the Profile Design website here: https://profile-design.com/...-aeria-ultimate-stem
Shows that it has 12.2 Angle.

The 2019 Canyon Speedmax CF Size Medium comes with a stem V21, 80mm, Angle -17 degrees.

Is it correct that I can remove the Canyon V21 80mm stem and use the Aeria Ultimate 70mm (or 100mm) Stem V2 and it will be the same angle?

Good question, I don't know though. I don't have the Aeria as of now. Maybe someone else can answer this. Try replying to canyonjay

The number you're looking at for the AU stem is the stack from base of the stem to the bar centre. Angles don't work so well for the dropped stem designs like AU or Syntace Flatforce.
The Canyon stem is fairly tall for a -17 so you'll be looking at ~15mm lower with the AU stem (I don't have the exact numbers to hand)

There does seem to be a typo in the product description on your website:
"Length: 70, 100mm (-12° only)"

It says the same next to stem length in the product selection button.

But then in the pictured diagram it shows 12.2m mm stack and 17 degree angle.

Hi Jay,


The reason why I'm reaching out is that you seem to be the expert on this topic :) I want to add the Aeria hydration system to my Speedmax CF 8.0 (frame size medium). I've read through this thread and the generic Speedmax one, but still have some questions:


So I get the part that I need to add the AU stem & hydration system. My local bike shop is gonna help out, but they asked for some guidance. What exact modifications are required afterwards? And do I also need to replace the current / stock bento box (see attach)?


I've also done a bike fit in the meantime and some spacers were added underneath the aero bars. Will switching to the Aeria system impact my positioning? If so, how can I return to a similar positioning while avoiding a new fit?


Thx!!

Spacers under the aero bar pads will be fine, switching the stem will not change that setup, only change will be bringing the handlebars slightly closer if using the 70mm or further if going with the 100mm (stock stem is 80mm IIRC).

The only modification I needed to do was to sand down the spacer. It works as a tongue in groove system with the standard stem. The aeria stem does not have the groove so it will not sit flush and you will not be able to screw the headset cap back on.

I also rerouted the front brake cable through the new stem, but that was very simple. I think the 100mm has another exit point that can be used for the right shifter cable but that's based on viewing photos from this forum. That would be a more complex cable to re route.

When using the stock 25mm spacer the bento sits flush with the top of the stem. If you slam your stem and remove the spacer and cut the steer tube there is a shorter bento that will sit flush with that setup.

I am currently having trouble with the bento rubbing against the stem when turning the handlebars >20° to the left. I think someone else reported theirs was also rubbing. You may want to look out for that.

It's a sweet setup when it comes together. I also replaced the bite valve with a CamelBak one and will be getting a longer tube. The stock bite valve wasn't giving the best flow but you can pop a CamelBak bite valve right in the existing tube easy peasy.

Have you been able to get the short bento?

I'm using the spacer so the stock bento sits flush, I don't have a need for the short bento.

Do you a pic of this setup?
I will be using a tririg brake up front so the stem appears to be set up for that already, but curious where you have the cable going into the stem. And for the rear cable, do you have it routed internall in the stem as well? How sharp a bend are brake cables able to take in situations like these? it would so much better if the canyon base bar had a hole cut out where the stem clamps on

Hi,


Does anyone have experience in assembling Aeria Ultimate Hydration with Speedmax CF XS size. Just got mine shipped and I noticed that there is very little space between the front brake and stem.

Not an XS, but I took some measurements with my medium. There's 2.5" between bottom of the hydration to the brake mounting bolts. Less for you I assume. Also to note, this is with the 40mm spacer under the stem that the Speedmax ships with
With the ultegra brake your cable won't be hidden.
With a tririg brake, I imagine the hydration would overlap the brake a bit but shouldn't be a problem. There's plenty of space behind the bottle and under the fairing

Did some math an it seems that in my case the space from the bottom of the hydration to the brake mounting bolts will be 23mm. Can someone be that kind and check on his/her Aeria this measure from the picture?

I'm wondering the same. Mine will be arriving on the 2nd and I'm really interested in this set-up, if the front end of my bike has room.

Thank for your reply Ryanppax

This means that there is only 1,3cm of free space between the bottom of the hydration to the brake mounting bolts. So it will be quite difficult to fit that Aeria there with fully functional front brake. Probably I will have to swap my front brake for Tririg Omega or something.

Anyway thanks for the measures.

Did you end up trying this? I'd really like to try this setup with my own XS CF...if there's any chance that it will fit.

For now this 'project' is on-hold. Decided to invest in the racing wheels first. Then - if my wallet allows - I will return to Aeria.

I totally get this. Hmm...I wonder if they're difficult with returns if I were to order it and have it not fit. My birthday is in ~2 weeks, so this would be a pretty cool birthday present.

I got this bottle fitted with my frame when I got my bikefitting but I holded it in hand (unfortunately they didn't have any Aeria stem in stock). It looked like it is 'doable' but for sure it will require some tweaks. I have an idea how to install it but I need to have the stem and the bottle together to be sure it will work. Also I could always change the front brake to Tririg Omega but in Poland it is very expensive (taxes, customs fee etc.)

I wonder if they aren't taking into account any tweaks. Man, I wish there were someone out there who has tried this who can verify that it will work. Granted, it would end up being a very $$ solution, so I'll probably end up with something less pricey, but also less sleek.

Did anybody ever have any luck fitting the Aeria HSF to an XS Speedmax CF.
I see you can not get a stem clamp to allow fitting the HSF to the Profile Seventeen stem (lighter and cheaper stem option.....)

Also interested in hydration options for a CF in size XS. Thanks!

Can the new stem front plate be used rather than the full PD stem

No. The bolt spacing is close but the wraparound on the bar is different so it won't work.

I'm thinking about getting the Aeria 100mm stem for my L Canyon Speedmax CF.

From what I read replacing the original stem should be quite simple apart from sanding down the stock spacer in order to fit flush, is that correct? Also the Aeria hydration system should then just fit right?

The Shimano break cable and shifter cables are not routed through the stem anyway, so that shouldn't be a concern right?

Also you seem to have noted some rubbing of the stem on the bento box? That doesn't sound too reassuring :/

Thanks!!

I'm using this exact setup except for the spacer as I run the stem slammed. Hydration will indeed fit.
Since I've lowered the stem, I also ordered the lower version of the bento which fits perfectly, I'm not noticing any rubbing between stem/bento.
For the cables, I've routed both brake cables through the stem, with the rear cable exiting behind the top-cap and front brake cable (for Tririg Omega) entering on the side and exiting through the bottom hole; this one was a real pita to setup! Had to route the inner cable first and then slide the outer cable in place, I had to remove the stem from the bike and also remove the basebar for this as the bends were too tight to pass the cables with stem and basebar all attached.
Despite all this still very happy with result!

Great, thanks!

The routing of the cables is optional though since they are not routed through the V21 stock stem, right?
I mean it would be a nice thing to clean up the cables but yeah.. I'm not so big about that. I'm mainly aiming for the 10mm added reach and the hydration system :)

If you want more reach and you're not fussed about internal cables why not get the 1/seventeen stem and HSF faceplate. Then you could go with a 110mm stem. Plus it would be lighter and cheaper. Not as low if that matters.

You're right, cables are not routed through the Canyon stem. Just did it to clean up the front-end.
Since I was lowering the stem, I had to redo the cables anyway so instead of a 30min job I turned it into an evening-long struggle :-)

Awesome, that sounds like a good option, didn't know about this, thanks!
I'd maybe even go for the 120mm stem (to have some room in forward and backwards; currently it's maxed out to the front with the 90mm stem)

For me that evening-long struggle would probably be a whole weekend ;) Thanks!

haha, well, I think it wouldn't be too bad to try... always rewarding to do your own bike-work and end up with a good end-result!
I also had to reroute my shifter cables and lost most time figuring out how the ^%#%^ I could get the front-brake cable routed.
As a side-note, maybe you could also add the Omega front-brake, together with Aeria/hydration and cable clean-up, you will get the real "super-bike" look for a fraction of the price!

I'm not sure the shroud reaches the frame with a 120mm stem, I'll try to have a look tomorrow.
I rate the HSF faceplate as one of my better ideas in the last couple of years - a small part making the fast bottle more affordable with more fit options.

That'd be awesome, thanks!

Do you find not having enough space for anything with the short bento?
I already have trouble fitting stuff in the current one and the di2 box doesn't help

I'm on a mech. groupset so that helps.
For 1/4 (oly), I can take my 4 gels with this box (gels sticking out) For longer distance I also have to tape some to the top-tube (and take the after swim gel in t1 instead of early on the bike)
Actually thinking of putting the high bento back on for 1/2 distance...

Tststs... Cleaning up the cables but taping gels to the top tube. Aerodynamically this is far from ideal, especially on long course. I'm sure you'll find a better alternative ;)

I'll use aero tape :-D
But seriously, I think the aero impact of gels on top tube is very small; and this is still better than gels+dangling cables...
Best solution though is to skip the long races (short races are more fun anyway ;-)

Yea, Id imagine it would have little impact sitting behind the bento. But what do I know?

This is with a 100mm stem (which is what the shroud was designed for).
It would be close on a 110 but with a 120 the shroud will be waving at the frame from a distance

Thanks! Interesting that Profile Design never mentions this. They only say the stem should be 90mm upwards. I'd like to have the 120mm though :/ Maybe I try it and see how 'bad' it really is

A question regarding the 1/seventeen stem. It doesn't seem to have a cap, nor does the Canyon V21 stem have a cap. So how to close the top of the 1/seventeen stem then? I'm generally little bit worried that the front might look completely off with a different, non-Canyon, stem

The headset cap is part of the steerer expander, unless it's a stem with non standard shaping.
I can't find a manual - but from the pics it looks like V21 may have a standard cap underneath the cover?
If it doesn't you will need to find something appropriate to the expander. If you're lucky that will just be a standard round cap with a bolt through the middle.

The V21 stem seems 1-piece, so don't think there's a cap somewhere. Hmm.. Gonna think about it, little worried the front might look completely frankenstein'd :/

That's exactly what I was thinking, the 100m aeria on the Speedmax CF 8 Di2

What'd you end up doing? Did it fit?

I didn't buy it. For now I've got a Xlab Torpedo hydration system. I don't quite like the look of a non-Canyon stem I guess :/

Hi,

Just received my Canyon Cf8. Starting to install the Aeria system. .

Original setup


Canyon stem and Aeria stem

Stem spacer with alignment tab (tab fits into the original Canyon stem)





Cutting away the alignment tab

First hurdle ; )

How did you manage to lock the Aeria stem cap as Aeria uses a 6mm diameter hole with an M6 thread screw. The original canyon one is an M4 thread. Just wondering as I did not recall anyone mentioning having this issue . How did you do it ?
I can use an M6 screw and machine/tap down its end into an M4 thread so its head still fits nicely in the Aeria cap and its end in the M4 thread of the Canyon tube. But maybe there is simpler way?





Also looks like with the Aeria cap being open ended to let cables pass through, it will not fully shield the steering tube from rain. Seems, it would be easy for rain/water to end up in the steering tube and create rust issue on the long run. Any trick to avoid this ?
Thanks,


FG

Look again. I think the stem "cap" is solid with no holes, like any other cap. And then the hole is above that with additional material to create a fairing of sorts to follow the shape of the rest of the stem.

Uhm, I just checked again. Not sure if I understand what you mean by "solid" stem cap.
Looking at the original aeria installation procedure, looks like "stem cap" is supposed to be locked via M6 screw into the headset tube. Canyon cap locks into it via M4 screw and the canyon cap as a slight groove/overhang that prevent water to easily get stuck into headtube.

So still wondering how people have been able to lock the Aeria stem cover/cap with this M6 screw since Canyon uses an M4.

Original Aeria installation procedure
No mention of using different size screw or seal/cap to prevent water from going inside head tube







Aeria and Canyon caps (side by side)




Canyon's cap is a solid cap that seats on top of the head tube. Its groove locks around/seals around the top of the headtube thus limit risk of water ingress.

Original CanyonM4 screw from canyon (plastic cap removed)

Oh so the issue is that you're using the Canyon cap. The Aeria cap fully covers the steerer tube. Why not use the Aeria cap with a washer and that M4 screw?

Good suggestion.
Actually, I was trying to use the Aeria cap.
But reading your comment, I guess the issue is me just being too picky and expecting profile design to provide accessories for a perfect engineering fit ; )
As per your suggestion, I will use the M4 screw from Canyon for the time being before I machine a custom one .

Aeria cap with M4 screw.





I am still concerned about water being able to find its way into the headset tube though.(see blue arrow on the pic). I live in tropical climate. Combined with both the proximity of sea and the high mineral/salt content of local well water used for rinsing bikes , this makes it a very hard on equipment and favors corrosion.

I don't feel like removing the Aeria cap every time it rains or I wash my bike to dry the inside of the headset tube. Guess I will have to 3D print a small plastic cap to close the top of the steerer tube (blue arrow on the picture).
I also make a custom M6 head/M4 thread screw. Very traumatizing for me to use an M4 head in a M6 countersunk hole ; )) In our workshop, we avoid to do this in the outdoor equipment we manufacture as using undersized screw in countersunk hole creates a little puddle/space for water to sit on top of the head of the screw and exacerbate the corrosion issue.



Seems some suppliers on Aliexpress are actually providing Aeria kit with "head expender" (not sure how to call this) that would address the issue of closing the steerer tube. Did not see such option available on the Profile design website.

Issue could be ordering from Ali. I've ordered multiple of these stems from local dealers and always came with the expander.

Sure enough though, just looked at mine and there is a gap, although a much smaller one.

The top of the steerer tube should be several mm below the top of the stem, otherwise you won't be able to preload the headset. In your picture it looks like the steerer is sticking past the top of the stem.

It looks like the Aliexpress images are of version 1, which had a different cap that required it's own compression plug
You have a V2 stem which stopped including the compression plug as the cap doesn't need anything special. Unless you have a bike that uses an uncommon small size bolt like M4
Water should pass all the way through the fork and out the legs - do you see drainage holes near the dropouts?

So I ended with PD FC-35



There was some difficulties with mounting it because of Subsonic's extended diameter (FC35 brackets cannot embrace it) but I used parts from the older bracket with straps....



At first I used given velcro straps but had an impression that it didn't hold the bottle as tight as I wish to and the assembly was bit flimsy. Changed it to good ol' zip ties and seems like FC is sitting tight between the bars...








Of course it is not so sleek and sexy as AU but I decided to go with something bit more affordable (Black Friday haul ;-) 1/3 of the AU price) and it doesn't looks so bad. Frankly it looks better when you see it with your own eyes that on the photos. Hope this helps...

Hi All,

Pls excuse for reviving this thread. I simply ordered the Aeria faceplate which mounted nicely to my speedmax with the original bolts.

Overall fitment is pretty nice, of course not 100% with some gaps between the original stem and the bottle...

Just wondering about 2 things:

- the front brake cable is pushing the rubber a bit away from the frame as it is exiting the brake from the side...
- why I would use this Garmin mount directly in the wind, this must cost some watts... maybe I find a mount for the stem cap



Cheers

See cyclenutz posts. Unless he can confirm that the bolt spacing, bolt angles, and bar wrap are identical, this is asking for trouble. Just change the stem before you have a catastrophic failure

Hi guys,
Below is a photo of my Speedmax with Aeria Hydration + Aeria Stem. Everything fits perfectly but I have the Top Cap from the Specialized set, from Aeria Stem it did not fit as it should :) Thanks for the valuable tips I was guided by when choosing :)


Regards :)

What was the reasoning for dropping the stem? You seem to have plenty of pad space with the stem at the oem height

If you can, it's almost always faster to slam the basebar and add stack with risers. Usually waaaaay easier to adjust stack that way. A lower basebar position also drops your center of gravity and will let you corner better as well.

Does your bike have a carbon steerer tube? If so, does the expander plug actually go all the way down to where the stem is clamped? If not, you need to trim the steerer tube at least until it does. Probably should trim it regardless since you're able to adjust stack via risers

With my fit I am using the subsonic bracket and 1 5mm(prefer 0) so that I can rotate the pads to 25 degrees. My pads are also as far forward as they can go with the 100mm stem. I'd love to take the stem down 2 cm but I figure the trade off of a slimmer bento or not cutting the steerer tube wasn't worth it.

The main reason for lowering the stem was to get a more aggressive position during the fitting. I was expecting pad spacers to be insufficient. During the fitting, however, I was surprised because we managed to pull the goal (head and back in one line) without lowering my body significantly. However, I didn't lift the stem any higher after fitting because I like to keep my hands (especially on the home trainer while resting) where the red arrows in the picture, I have a place now. The second reason is the bike looks better ;) Fitting results in the photo :)

How did you resolve this? Did you end up making the custom head/thread screw? Did you 3D print a steerer tube cap? Would you mind sharing?
I have a CF 8 (eTap, same brake cable positions), Aeria stems (70 & 100) and the hydration unit arriving Tuesday.
I'd like to have this sorted ahead of an upcoming fit in two weeks a couple hours away and determine stem length at that time.
Thanks!

you can use a regular flat stem cap

Dealing with the stock spacer before changing stems. Did you just cut the alignment tab? I'm trying to switch to the PD 1/seventeen stem, and it looks like I'll need to cut off the circle that sticks up from the stock spacer as well as that short tab that lines up with Canyon's stem so that the PD stem will fit.

Anyone done this? Good idea/bad idea? Should I just buy a different spacer?

Thanks!

Yeah, no problem in cutting it. its no big deal. Dremel might be easier than cutting.

Hi guys! I have the new Speedmax CF 8.0 Di2 DISC that has a different geometry than the rim brake one. Have been looking for a way to use the Aeria Hydration on it but haven't found other info than the one that involves in changing the stem to the Profile Design one that won't look good a all.

As a layman, I'm thinking that a face plate, much like the Profile Design HSF 1/17 one, would be a way to go. Unfortunately that face plate doesn't match the Canyon v21 stem according to Profile Design. Canyon does however make a v21 in 90 mm that will be large enough to fit the hydration system.

So I was wondering if there's anyone out there who might be willing to create a CAD model of a face plate that on one side is like the PD HSF for mounting the Aeria hydration system and on the inner side, having the holes that matches the Canyon v21 stem.

I know that 3d-printing in aluminum isn't cheap and I'm too much of a novice to know if that print would meet all the requisites needed for it to be safe to use but I'm sure there are someone out there who might know or at least, point me in the direction of someone who might know.

I'm sure there are many of us who would find such and adapter very useful and I for one, am willing to pay for that. :) I live in Sweden in case there's someone close enough willing to see the parts personally.


https://www.profile-design-eu.com/...-hsf-aeria-faceplate

https://www.canyon.com/...m-medium/106426.html

Apparently it fits without issue??

Wooooow! You really made my day! I've b een in contact with Profile Design previously and they assured me that the adapter wouldn't fit. Now it seems it works perfectly! Thank you so much for taking the time to post. Awesome!

It fits, but that doesn't mean you should do it. Product Warning

The bolt spacing matches but the bar wraparound is not the same. The configuration has not been safety tested and is specifically recommended against

Also, 3D printed aluminium or even a custom cnc part would be a bad idea.
A lot of testing goes into the parts that hit the market

FYI, I'm the product design consultant for PD that came up with the HSF faceplate (among other things). It's a simple product but there is a lot behind it

Thank you for responding! Any thoughts on the stem's fitment with the CF8 requiring irreversible changes to the bike (cutting) and the other fitment issues mentioned? I'd love to be using this system, and have had issues with a few of the other PD products available.

Well that made my day, being the day I didn't crash on the bike, hahaha. I knew it was too good to be true. Thanks! What i just can't understand is why they (Canyon or PD) come up with a functional adapter. It would sell like ice cream on a sunny day and be in both companies interest. They had some similar system om the SLX rim brake version but nothing on the new one and I can't understand for the life of me why they decided to just not offer a valid solution. The stem on the old SLX is not the same on the CF disc one so getting the old stem is to get the canyon hydration system is not even an option.

As of now I'm using the PD FC 35 and it looks terrible. Even worse is that it takes for ever to get that thing on and off.

We've been discussing that since long before the bike was released. The problem is that the nosecone on the frame means that a specific faceplate would only be viable for the longer Canyon stems. So it wouldn't be a universal solution and we don't want to be sizist.

The topic comes up every week because of the frequency of enquiries and the volume Canyon is selling. But with the lead time on new alloy production - by the time we got anything new to market the Canyon set up will likely change. Feel a bit painted into a corner on this.

I've not tried to fit either the 1/seventeen or AU stems to the CF (rim or disc). If I were to do it - I'd just go with the 1/seventeen stem (unless you need the drop of the AU) as you can't take advantage of the internal routing with the Canyon bar anyway. Neither PD stem matches the design language of the Bento so you're relying on the bottle to hide the stem in both cases. 1/seventeen is much lighter and cheaper than AU.

What issues have you had with PD products?

Actually the stem lenght of size S and M is the same - 80 mm. The guy on the video has a size M so that means that an adapter plate would work on all but the XS model. Besides, Canyon just launched this model so the frame will most likely be around for at least two more generations. I can't understand why - and yes I am a layman - a thing as simple as making those small adjustments needed could be done? I mean, many want this to work and if you hadn't posted the warning I would've order the HSF faceplate within a few minutes. if a lot of people do that without knowing, accidents might happen and that wouldn't only be bad for the poor person faceplanting on the tarmac but a hard blow to the company brand.

PD and Canyon have worked together closely for years. How come this is a tough nut to crack?

Cyclenutnz, are you in any way affiliated with Canyon or PD or have an insight there on the matter?

EDIT: Sorry the refesh rate is a bit slow. Just read that you've been working with the HSF face plate. :) Thanks for taking the time to answer the queries regarding this. So no that you have a hands on experience, do you have any suggestion to find a solution? Would it really be that impossible to expect a variation of the faceplate that fits the v21?

Did I send you that image via email?
You can see that the clearance on the CF Disc frame with a 110mm stem is less than 20mm. By leaving the tall spacer in he may just have rubber hitting the frame but even that is a risk.
If we create something that has too many caveats it just generates more hassle and risk of harm.

Frames normally have a 6 year life cycle, other parts may change in that span. PD have a new bottle in the works, I can't speak for Canyon.


As I mentioned - we discuss this constantly and have been since early 2019. There are a whole bunch of small factors that add up to make it a more complicated topic than it appears. We may come up with a way to deal with it but currently there isn't a clear path.

I see, thanks for clarifying and taking the time. I guess I'm just too eager to get back to the best hydration on the market. Love the new bike but hate not being able to use the Aeria on it.

Looking forward to news about the new bottle then. Is there anything you can disclose at this time? Will it be a front hydration as well or something else? If front hydration, will there be compatibility with the V21 then? :)

It is unfortunate, it's the best speed/$ upgrade for most bikes


It's a new version oriented towards disc brake bikes (don't have to allow for a rim brake caliper) but not good with nosecones I'm afraid.

Is the bottle in this picture the new one? Also, which 110mm stem is that and whats the stack height?

Sad to hear. :( Are you able to say anything about the releasedate? Is it an upgrade to the Aeria you are talking about or is it a completely new thing? :)

That's the HSF Aeria without rubber fairing on (hard to see clearance if it's on)
The stem doesn't exist yet, stack same as normal -17, longest will be 105mm (110 was an early design iteration sorry)
Working away on my goal of making 'mortal' bikes super.
ETA - who knows. As mentioned - alloy is quite a problem.

HSF Aeria will continue for a while yet as the new one does some different things.
It's got a bunch of different features to the HSF Aeria
Release date quite a way off, bottle moulding is complicated.

Looking forward to it! :)

How tall is the steerer clamp on the new stem? I trimmed my steerer for the V21 stem without 25mm spacer installed, since spacers on top aren't possible. I think it has a ~36mm clamp height.

The profile of the new stem looks really nice

clamp height will be in the 34-36 zone as far as I recall
The stem should be quite useful

Music to my ears. Just need a basebar with a clap area exit hole and FSA compression plug to really clean up the cables on mortal bikes.

Do you know whether the Canyon steerer tube cavity and fork cavity are continuous to route the front brake hose that way?

I'd shine a light in at the brake cable exit on the fork leg and look down the steerer to check.
But it should be - monocoque construction means the bladder is Y shaped and gets pulled out of the steerer

All the things on your wishlist are part of the plan.

Nice to hear about the wishlist! I think I'll hold off on this project until these things are released to do it all at once. Sounds great. Looked like the wing/20c already has that port but it's not the most aero looking basebar. Add that port to the Svet bars, please ;)

Svet bars won't be continuing, Wing20C and WingC are it. I feel you should look at the W20C more closely, there are reasons for everything.

Fair enough. I'm assuming the thickness and blunt rear is for stiffness and volume to accommodate cables better?

Btw I love the Subsonic bracket. Nice way to reduce frontal area vs undermounting. But is there any possibility of a longer pad reach version coming that has the cup mount surface in line or in front of the bar clamp? I have the Race cups all the way forward and that basically centers the cups with the bar clamp.

Bumping to add my latest iteration to this solution and I think will be the one to stick. Added the Aeroport and bar end junction A ditching the 5port junction. I stuffed the junction B into the stem and wired everything that way. I also decided to route the front brake cable externally. With the canyon base bar the cable just bends too much to route thru the stem and I was never happy with the performance. With the external cable route I have never had better actuation with the tri rig brake, and it is still well hidden behind the fairing. I will probably cut a little cutout in the fairing.

Reviving a bit of an old comment...

I recently picked up an aeria ultimate stem for my 2019 rim brake speedmax. I'm noticing the same issue where the current V21 stem uses an M4 bolt but the aeria is supplied with an M6. Is there a recommended solution for a proper fit or is it recommended to use the M4 bolt from the Canyon and just have it not fit as nicely?

Thanks!

Do you mean the bolt for the headset top cap into the steerer expander?
If so, you either need a new expander or just use a countersunk M4 bolt and accept it sitting a little lower than the AU original

That’s right, the top cap bolt. Sure, I’ll just use the one that came with the bike for now and get a new expander to use the appropriate bolt the next time I’m having something else done by my LBS (maybe like putting on that wing 20/c for invisible wires…)

Thanks!

I have a CF, had no issue with removing the spacer that came with the bike and using a bearing cap from another bike. #slamthatstem
