Thanks for the contact.
So here is bike situation- year on borrowed too small bike- twitchy. Three years on used QR 4/5- very stable in XL- slammed front end, seat forward of BB a little, fit pretty good. Looking to upgrade to lightly used slx rim brake ultegra in large from friend who is enamoured with 21 models.
Just under 6’2’’, 33.5 inseam, 74†reach
187 pounds
My measures are not perfect here but close
Pad stack 675
Pad reach 530 to Center
Seat height 790
172.5 cranks
Aero bars angled some to get back of pads down and like some angle
Looking to get front end down to 640’s ish
Pads could come back a little
Like to go to 165-170 on cranks
Shorter course racing preferred. Maybe 70.3 some day
Like to mash it hard on the 53-12 and run fast. Sub 18 5k with good flexibility for age 50. Decathlete background and body type.
Thanks-
CamoMan,
For the 2019-2020 rim brake Speedmax SLX you’re a size Large. That bike can make your current Pad Y of 675 (with 45mm of pedestal) or the goal of 640 (with 10mm of spacer). Clearly the 165mm cranks will help you get closer to 640. The Pad X (current 520 or shorter to 500) all with the short cockpit that came stock on the bike. You’re really right on for this bike.
#1: already have the full 45mm spacing under my aerobars #2: I can order the Canyon High Stack Spring Kit (GP0157-01) #3: no mentioning of Team Switch Plate on Dutch Canyon website, have sent mail to support team.
And searching for Canyon CF SLX and 51 Speedshop, I found below photo. Any thoughts on this (pads seem higher, right)?
Best regards,
Erik
Erik,
The High Stack Flat Spring will get you up higher. Do you happen to know how much higher you need to go? I ask this knowing that every human on the planet should be pre-fit on a dynamic fit bike by someone who knows what they are doing before they buy so that Pad Y (what we’re talking about here) and Pad X can be determined before someone buys the bike. It can’t always happen that way but… I can dream!
If you’ve maxed out the pedestal on your 2020 Speedmax SLX then you’re at 640. When you put the High Stack Flat Spring in there you’ll be at 650. The bike is not intended to go higher than that and even if we use the TSP and thicker pads - there’s gonna be an end to this elevation. Will 650 satisfy you? Will you need 653? What is the Pad Y goal?
As to this picture… Hmmm… there’s very little that is stock on this bike (wheel, pulleys, cranks) even the extensions look like 51-Ski Carbon Extension installed…??backward?? The pads look like 51-Speedshop too, but I don’t think that’s their 51-Mono-Riser Aerobar System. Regarding the 51 Speed Shop front end (I’m mean the whole thing) I’m not sure it will fit, if you can get one (site says they sold out), and if you could find one if that would put you higher than 650 - so lots of questions on that. I would go HERE, hit the contact us button and tell Matt that I “Ian sent you from the Slowtwitch Canyon thread” - ask him. I’d also try to contact someone HERE or DM TriRig here on Slowtwitch and see if that bar would take your 2020 SLX higher than 650.
I’d love it if you got back to me here with what you learn on those two fronts.
I am reevaluating my size choice for a CFR/SLX. I could still adjust it with Canyon.
Pad x: 505 mm
Pad y: 680 mm, maxed out the spacers on the previous SLX.
Inseam 97 cm
Body size 192 cm
Seat hight 840 mm
I had to change it slightly to my latest bike fitting data.
I feel like I might have to go with. XL and a short stem? Would that work?
Canyon suggested an L and a long stem. Though I put in the wrong inseam of 91 when I submitted my data.
My frame size on the old rim brake SLX was L with a short stem.
Hi, Ian. Amazing help through this entire thread! I’m also one of the many looking at a Speedmax (7 or 8 disc). Would appreciate it if you could take a look at my own numbers. Maybe give me and idea of frame size and what I’d need to do, if anything, to get the factory bike fit to my measurements. Thanks!

VooDoo90,
The previous model - the rim brake SLX was a very long and very low bike. This new one… not so much.
For the Canyon Speedmax SLX size Large the Pad X maxes out at 504 with everything (long stem, pads pushed to the max). If 505 is your Pad X, and I see no reason to doubt that, then you need to get the XL. And the XL will be perfect for you with all the stock stuff: short stem, mid spacer, mid aero extension, etc. etc.
Ian.
I am looking to buy the CF 7.0 disc. Not sure on the size, could you help?
Pad reach: 499
Pad stack: 707
Pad height: 60
Pad offset: 50
Pad center to center: 270
SX: 135
SY: 684
HX: 549
HY: 647
I am 5’10 with a 32 in inseam.
SoonerBorn,
Let me answer your direct question first - if your Pad Y is 707 and your Pad X is 499 and your seat height is 761 (had to pull that number off you’re other post) then the right Speedmax SLX for you is a size Large. And the seat post will be well down in the frame.
Now… if you’ll permit me… I’d like to share some thoughts that combine this post and some info from the “sizing question” post of May 17th. You’re making me work for this one: critical numbers and info spread across two posts one of which is me just stumbling on it!
You’re pretty leggy for a guy who’s 5’10" and that’ll work. There are lots of us with that morphology. I’m pretty content with your Pad X of 499. I would have guessed 480 but that’s in the neighborhood. Your Pad Y of 707 however is suspect to me. I would have thought a 650 would be more logical. I don’t have much to go on so you might have 4 fused lumbar vertebrae and if so - 707 is prolly right. You might have a sizeable beer belly. If so the 707 is justified. But… if you’re fit, normal, healthy… then I worry something has gone awry. And I… as not just a bike fitter, but a bike fit instructor, and a triathlon coach have to inquire… what saddle was used in this fit, where where you sitting it, and was it comfortable? I ask this because if you’re hips are behind the bottom bracket more than desired you can’t get low. In the other post you suggested the set-back is 30mm okay, maybe, but you better sitting on the front half of the saddle. I also wonder - what length crank was used for this fit? I ask this because you should probably be on 160-165mm cranks and if you were on something longer then it’s harder to get low.
I’d like to keep working with you on this here if you’re willing.
Are you injury free/healthy/fit(ish)?
Tell me about your fit experience:
were you in a cycling kit and clipping in?
everything you can remember about the saddle and how you were comported upon it?

Hi Ian,
Thank you so much for the advice. In my calculation I ended up with the XL model and a short stem too. Though, as my forearm length is 39-40 cm I would go with the ling extensions. Extension length has always been a problem and the only ones so far that fit were the Zipp Vuka.
The frame size was important though. I changed it with Canyon. Looking forward to all the adjustments.

Voodoo90,
You are welcome, I’m glad I could help. And good point on the long extension!

I was measured using saddle height referenced from BB. I did some interpretation from there. Here’s the plain text of my fit:
*Saddle Height (crank-center to saddle-top-midpoint): 72
*Pad Drop (saddle-top-midpoint to pad): 7
**Saddle-nose to pad: 50 (my BB offset from saddle-top-midpoint was 0)
ctbrus,
You ride long! I would have put your Pad X at 460 and you’re out to 500. That’s long. It’s so long that I would be worried that it was a typo but you back it up with this nose-of-saddle-zero-setback addition. But you also speak to some “interpretation” so maybe it’s not 500.?? I’m not sure but you’re height - inseam ratio are logical, normal so I don’t see how/why you are at Pad X - UNLESS! This was measured to the center of the pad! That’s gotta be it!
I’m gonna prescribe a Speedmax CF based on this info: Seat Height of 720, a Pad Y of 650, and a Pad X of 460 to the rear of the pad. Seat Height is great. The Pad Y for that is great, right in the center. The Pad X will happen with the 80mm stem that comes stock and pads pushed out 100%.
Let me know if I’m wrong about my guess that Pad X 500 is to the center. The bike can still work but we have to get creative.
Hi, Ian. Thanks for the help! By “interpretation” I meant trying to transpose my fit measurements that used the saddle nose as a reference point vs BB. We are talking pad center from my memory… another measurement: cockpit -sdl nose to shifter pivot- is 81cm if that gives you any more insight (??)
Are you thinking a small frame with the fit considerations? It looked like from the Canyon ht/inseam guide it was spitting that out but I was close to a medium. I’m currently on a 52cm Kestrel and it feels pretty compact. Whatever gives me more flexibility to dial in the fit is my best bet, though!

The small fits you best because of seat height - like many folks, your Pad Y/X could work on a couple of sizes - for you it’s a Small or Medium. The small is a better fit for you even with the pads pushed forward 100% and if (in the extremely unlikely event) that you’d want to ride longer you’d just get a 90mm stem from Canyon and you’d have it.
I’m looking to buy my first tri specific bike, and i like the speedmax cf slx.
The canyon website puts me in a medium, but all thats available is a large, could that work for me?
I’ve got no pad x and y measurements…
Height: 183 cm
Inseam: 84,5 cm
Saddle height on roadbike (fitted): 765mm with 172,5 cranks.
Im pretty flexible and do not have a beer belly

Max,
Well… no beer belly, healthy flexible… and pretty leggy for your height. I bet your Pad Y is roughly 655 and Pad X ~480. Based on that I think the disc brake SLX is better for you in a Large than a Medium (although both would work). You’ll be able to use the short stem that comes stock on that bike in the USA and just push the pads forward… quite a bit. If you’re ordering in the US the mid spacer will come on the bike, you can ride for a bit but I think you might be able to drop down to the low spacer.
I see that Canyon has the rim brake SLX for sale at $2000 off in the US if that’s the bike you are in interested in let me know as the prescription is very different.
I’m planning to buy a CF 8.0 rim brakes. Height: 170cm - Inseam: 78cm
S size is what the canyon site is proposing but I was wondering if XS will work too? As it is the only one available now.
Unfortunately I don’t have any other data. It will be my first TT/road bike.
