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.

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.
