Hi Ian!
I'm a short triathlete, 164 cm height.
Inseam 78 cm.
BB to saddle 68.8cm
y=625, x=430.
Crank arms 165mm.
Currently on an Orbea Ordu which I love but it lacks elegant and comfy nutrition and hydration solutions :-( for my races which is typically 70.3...

Will I fit on a CF SLX small frame? Local fitter told me Speedmax bikes are too large for me since I don't want the xs due to their 650b wheels.
Thanks!

Hey Ian,

looking to purchase my first tri bike and really like the speedmax cf slx 8. I have been at a store and had a testride one the size S with a very small fitting at a canyon store nearby. The employee said from the measuremeants i am pretty inbetween a size s and xs. After the tryout he seemed to be happy with me on the former one.
Doing some more reading once i got home i now regret not trying out the on in xs aswell. I was hoping that maybe you could give me some more insight here.
hight: 168cm
inseam: 80.7cm
forearm: 34cm
As i dont have a tribike yet i sadly dont have any more measuremeants. I believe the bike i tried had a medium aeore bar extension one, which we slammed all the way back. I was advised to chose a extension size small and then would be good with adjusting it.
Appreciate your help!

rswo23,
The test ride process doesn't work well on modern bikes because there are some many adjustments that can be made - but no one is willing to take so much time to adjust/ride/adjust/ride it's just NOT logical. Have a fit done on a dynamic fit bike is the best way but I can speculate here as well. Based on your morphology I think your Pad Y is ~595 and your Pad X is roughly 440. I'm pretty certain the XS will be too short for you so...

Canyon Speedmax CF size Small with the 70mm stem that comes stock. I think you'll ride it pretty low so leave the ~25mm spacer under the stem and slam the aerobars - you can always add spacers and screws to pedestal the aerobars higher if you need them up a bit. Also, that Pad X I'm guessing at (440) is just ahead of center of the small range so you'll be able to pull your pads back 50+mm and push them forward nearly 30mm.

Ian

Thanks a lot so far!
Sadly my fitter where i live doesnt offer a dynamic fit bike. Is there a difference between the frame sizes from the cf slx and the regular cf? Definitley helps to have another opinion on the xs version beeing to small for me. The regular sizing chart from canyon based on hight just threw me off a little.

Hi Ian

would appreciate your advice on sizing, i'm considering a CFR or CF SLX depending on what's available. Currently on a small Scott Plasma 5.

Pad X - 420
Pad Y - 620
Saddle Height - 715 (might drop a few mm as i'm likely to move to speedplay from Look Blades)
Inseam - 840
Height 1730
Tip of saddle to end of shifter - 805

I feel like i could stretch out a little more on my current set up and often find myself brnging my elbows back to the back of the pads.

15 degree angle on by bars currently with D2Z angled poles too.

Hi Ian
I don’t have a Tri Bike so don’t have Pad X and Y measurements. I’ve (hopefully) attached in a photo some measurements for my fit on my Endurace road bike which is a size L and fits great.
I am 185cm with Inseam of 85cm.
Canyon calculator puts me on a large Road bike but M Speedmax CF Disc.
I did notice earlier in the thread that the older rim brake Speedmax has a shorter top tube and I wonder if I would be ok on an L size in one of those as there is one for sale second hand locally. In other news I have very tight 50 year old hamstrings and wonder if I should just stay on my road bike!!
Thanks very much for your help.

Hi Ian - following all the fits I was wondering if you had a list of spacer extensions available for the speedmax SLX (2020-23 model). Like the radsport ibert one. The cockpit was clearly a design flaw in terms of how short it is at the front for a lot of athletes. You would think canyon would acknowledge what’s happening with this and not hiding to mainstream customers

Hi Ian,
I've got a rim brake 2018 Speedmax CF 7.0 M which has a frame issue and am looking at either replacing or repairing the frame. I'm currently not able to get a medium in the Speedmax CF disc brake but could get a large or small based on available stock. My current measurements are:

Pad Stack - 665mm
Pad Reach - 427mm (to back of pad)
Seat Height - 747mm (170mm crank length)
Inseam - 850mm
Height - 180cm

Any advice as to whether a small or a large would be reasonable would be much appreciated (given that it may be a while before the mediums are back in stock). The stand-over height in the geometry chart for the large seems like it would be an issue - much higher than my current rim brake CF.

I don't have all of the stack/reach numbers, but am curious if you could provide some guidance. When I use the P.P.S. on Canyon's website, it asks for my height and inseam length, which is 73" and 34" respectively. That puts me at a medium. If I fudge either of the numbers by just a touch, it bumps me to a large. So that just gives me pause as I feel like I'm a "tweener" edge case sort of situation.

Both of my tri bikes in the past (QR CD0.1 and Argon 18 119+) have left me feeling too compact/compressed throughout my midsection. So my question is... is there an appreciable difference between the Medium and Large frames that I should consider if I were looking to stretch my front end out a little? I have a feeling I would be at the extreme end of a medium. Maybe I'm just curious how much overlap there is at the "long" end of the medium and the "short" end of the large.

Or am I overthinking things? I'll hangup and listen.

SBRcanuck, You are reading the prescriber correctly and I would argue that even getting the medium to 648 is a bummer because it requires an aftermarket item to lift you even further than the max of all the normal pieces. Are you a bad fit for a Canyon? No. This particular Canyon Speedmax SLX is a long and low bike and you need more of a longish and and taller bike. The Canyon Speedmax CF in a medium fits you VERY well. And, I've only been looking at the new numbers on the new disc brake Speedmax for 20min so I need more time to be sure but it looks like you'd fit on that bike well too.

Ian

Hi Ian, could I get your size thoughts on my numbers as well!
When looking at the Speedmax CF SLX, I seem to not necessarily fit well on any of them.
Stack - 64.5cm
reach (centre of pads) - 48cm
saddle height - 72.8
When I look at the charts, it looks like a small has a pad stack range of 566-619, so that won't work.
A medium has a pad stack range of 595 - 648, so just barely makes it?
The medium has a saddle height range listed as 727 - 857, so apparently I'd literally be on the limit of getting my saddle low enough, and obviously puts a large out of range with a 761 min saddle height.
Am I just a bad fit for Canyon?
Thx!

Hey Ian, just wondering if we could revisit this for the CF SLX as the geo charts seem different now in terms of the stack ranges.
My measurements are still pretty much the same as above..

My low saddle height maybe makes sense with a small, but the reach maybe a medium but not sure the medium would work with my saddle height, still seems too low to be in range...

Also, one other concern - with the size small frame, if I calculate the front center (not listed on their chart) by subtracting wheelbase from chainstay length, that gives a front center of 56.6cm.
My current 54cm Felt IA that fits well has a FC of 60.2cm. So the front wheel of the small Canyon seems like it would be 4cm firther back, major toe overlap and sharp handling??

Can anyone tell me what my stem options are for going LONGER on my Medium CF8? I can't find longer speedmax stems on the Canyon website for the CF8. Thank you

Hi, wondered if I could get some assistance before committing to the CFR or the SLX on the outlet store (an older model given the spares storage is at the proximal top tube)

At 181cm it seems I'd be a guaranteed medium from the height scales
Inner Leg 845mm

Last fit on a 2013 L Shiv
Pad Reach (BB to pad) 455
Pad Stack (BB to pad) 687
18mm from BB to saddle tip

Youngish, strong, flexible, competitive (2nd and 4th overall in last two Ironmans) so happy to aim for an aggressive position.

Do I actually need to consider a small given the reach, or a potentially different brand? Sorry I'm completely clueless on bikes/technical side so looking for any reassurance before my first proper purchase.

Measurements attached
