You should probably be using 155mm cranks.

Thank you for the background and history on what and where Pad-X and Pad-Y come from. Very intresting.

I'll take a stab at figuring out my pad-X and pad-Y from my old bike. If you are up for it I'll also ask you to take a stab at it. I figure getting 2 data points is significantly better than one.

My information:
Hight - 75in
Inseam - 34in
Oddities: none - pretty standard athletic build body

I'll see what you say vs my bike fitter cuz I'm genuinely curious....

Armpad stack: 727mm
Armpad reach: 413mm
Saddle height: 773mm
Saddle setback: -36mm
Armpad width: 253mm
170mm cranks (spin to win lol)

ThatDudeInPink,


which Speedmax? CF or SLX/CFR?

ThatDudeInPink,

I want start by imediatly answering your question: with a Pad Y of 727 and a Pad X of 413 the right Canyon Speedmax SLX does not exist, in fact there are few bikes built that will acheive those coordinates. You have the Y of a XL and the X of a Small. To get an idea of what an extreme outlier these numbers are plot your spot (727/413) on this graph. I want to help resolve this for many reason not the least of which is my own edification so please, stay with me on this...
Ian

Those are directly from my Retul bike fit. Inseam 33. Height 6ft. I’m checking again and yep… arm pad stack 727. Measured from the bottom bracket to vertical to top of arm pad. Arm pad reach 413. Measured from bottom bracket to horizontal back of arm pad.

PB4WEGO,
I think your Pad Y should be in the neighborhood of 690mm and your Pad X should be ~ 505. If you were to get the...

Canyon Speedmax CF (this is the "mortal bike" with a pretty normal stem on it) it would be the size Large with the 90mm stem that comes stock on that bike. This will give you room to up/down/fore/aft quite a bit to find your pefect spot. I thought - based on your height - that the XL might work too (and while it does in the Pad X) that size bottom's out at 690 so I worry that if you want to go lower (or I estimated too high in the Y) you won't be able to get down there.

Canyon Speedmax SLX (this is the "super bike" and this prescription is the same for the CFR model) size XL with the short stem, mid spacer, and medium extensions. You'll have lots of room to go up and down and shorter it cockpit but not a lot longer with this hardware. If you needed more cockpit than my guess of 505 would give then I want you to either get the long stem or the angle spacer from Rad Sport (which would give you some tilt as well).

Ian

ThatDudeInPink,
If you had come here and said something like "never owned a tri bike, I'm 6' tall and have a 33" inseam wadda ya got" I would have said... you're Pad Y is going to be in the neighborhood of 660 and your Pad X would ~470 - and keep in mind, that ARTICLE I referenced would still have you a bit "short and tall" in your coordinates but it's logical because you're kinda leggy for your height- as am I, as are many and when your legs are a bit longer and your torso a bit shorter you get a good position and one where the pads in that spot.

So now we're back to why are you riding at 727/413. It's unusual and so worth the exploration. I can think of a few posibilities:
1) You have 4-6 verterbrea that are fused in your lumbar area.
2) You were fit to a road bike with a road saddle and clip-on aerobars
3) You were fit to a tri bike with a road saddle and the seat angle is very shallow
4) You cannot apporach anything even close to the front of the saddle and by sliding back for comfort it kept you from getting longer/lower

Are any of those possible?

Ian

I was traveling back from a race. evidently the front axle was loose and now is lost. I can't find anywhere on the canyon site a replacement front thru axle for 2022 speedmax cfr. Can you assist?

thx!

Ian,
Probably getting a Speedmax CF SLX (from Canyon Canada), as they have a color I actually like--just not in stock so I may be waiting some time. I am right smack in the middle of a SMALL frame. Reading the thread on fit..you suggest:

1) Flat bar
2) Medium stem
3) What crank length--? I'm on 165's now...


Are there any other options you are aware of at time of ordering?

Measurements: 176.53 cm tall..
inseam is 81.28...s
Handlebar Reach: 461 mm
Handlebar drop: -155 mm
Arm Pad Reach: 418 mm
Arm Pad Drop: -82 mm
Grip Reach: 811 mm
Arm pad to Grip Reach: 392 mm
Pad width: 193 mm
Handlebar stack: 573 mm
Handlebar stack: 491 mm

I'm currently on Cervelo P3 2010 model size 56 cm. Even Canyon says order a size down from what you normally would & talked to them with inseam & height measurements this past week.

Hi Guys, hi Ian,

I'm about to buy new Speedmax CF SLX and it will be my first tribike. Now I'm riding Specialized Tarmac SL7 with clip-on aero bars, so my Pad X and Pad Y might not help here but let's give it a try.

Pad X - 375 mm
Pad Y - 640 mm
saddle height - 675 mm
height - 170 cm
inseam - 75 cm
forearm - 37 cm

I decided to go with size S and just wondering about stem and extensions length. My bike fitter told me to take everything as longest as possible, so that means long stem 85 mm and the largest extensions. Could you please confirm if that would be a good choice?
Thank you in advance.

Hello,
I'm planning on buying a speedmax cf slx as soon as it's available in the market. And I'm confused about the sizing.
I apparently sit on between size S and M.
I'm 178 cm tall with 83 cm inseam. and with that the recommendation is size S for the CF SLX. But M for The CF SL.
I have a canyon endurace in Size S, as I fit both S/M.
I'm currently riding an old BMC Timemachine road which I retrofitted for triathlon by swapping the cockpit to triathlon cockpit. Frame size is 56
Since I'm right in between frame size S and M for the speedmax cf slx, should I go up for M or stick to the recommend size S?
Thanks

ismail,
Super common for someone to be able to fit on two different size bikes. But in this case it must be said that the SLX and the CF are different bikes - both excellent but with different geometry and different front ends that have indivudal limitations in their adjustability. Based on what you've given me here (fairly long legs for your height) I suspect your Pad Y is ~640 and your Pad X is ~455

For the Speedmax SLX (or CFR, same geometry).... you're a size Medium with the short cockpit (read: stem), mid spacer, and medium extension. The bike will arrive with a box of goodies that include different spacers, wedges, and bolts that will allow you to adjust the aerobar height and add tilt if you want. The bike typically ships with the mid spacer and if I'm right about the 455 Pad X measurment then the mid spacer will work for you but you'll have all the tid-bits to make changes if need be. If you decide to get the CF you are a size Small in that bike and the 70mm stem that comes stock should work well for you.

I want to make one more note about this... your position on this tri bike will be different from what you've known on the retro fitted BMC and a far superiror tool for triathlon. The seat angle will be steeper with your hips nearly sitting atop the bottom bracket. There will be more weight on the front end and the cockpit will very likely be shorter so that your upper body weight sits on your humerus bones like a piller. It's fast, more comfortable to hold the aero position, and that's everything we want in a tri bike.

Ian, thanks a lot for the precious details.
I haven't done a proper bike fit for my current bike because it's only temporary solution until I'm able to buy a proper triathlon bike.

Today I have a bike sizing session that should also help me take the measurements more accurately.

I'm definitely not very comfortable with my current position on a road seatpost and can barely sustain it for a middle distance, even after moving the saddle as far forward as I could. Which I'm hoping to fix with the speedmax as soon as I can get my hands on it 😅

Fresh79,

Sorry to leave you hanging. Taking all of your input into consideration - and between the fit sheet, desire to prioritize comfort (respect!), etc., here's my thinking on the right Canyon Speedmax SLX for you. I think your Pad Y is ~675mm and your Pad X is calculated at 473 but I think you'd be happier at 490-500 (more on that in a sec). So... size large, flat bar, medium extension, and mid spacer- all that of that is certain.

Now let's get into the nitty girtty...
If you're ordering in the USA the bike will come with the short stem, flat bar and medium extension and you can't change that in the order process. If you're ordering in EU then I think you can specify what you want on the bike within the purchase process. The short stem will max out Pad X at ~483. You're currently at 473, I think you might go longer so 483 gets you 10mm more. If you go the long stem the range would be 450-505.

So if you're in the USA take the bike stock and if you want to go longer later get the Rad Sport tilt/extension thing. If you're in Europe get the long stem. No matter where you are get the flat bar and medium extension.

The bike comes with a box of spacers and bolts to detail the aerbar height. In the USA it'll come with the mid spacer and I think that'll be right for you but if you want to tweak the pad height it's easy to do and you'll have all the bits to do it.

Ian

Thanks again Ian! Love your work. Just a final question re the extension / stem measurements... my forearm measures 36cm from tip of elbow to centre of palm and 50cm from tip of elbow to end of my longest finger... do these values alter your view of the extension / stem lengths?

I am based in Australia, and to the best of my knowledge Canyon allows for some modification of the cockpit, i.e. I can choose a riser bar and short, medium, long extension lengths.

Paul,
This is good for me to know that Australia, like Europe, will let you build as you purchase. So get a size Large, get the long stem, flat bar, medium extension. If they let you choose which spacer sits under the aerobars get the mid one but I'm assuming that'll come stock with other pieces as options in the box.

Ian
