I am on the verge of pulling the trigger to order an Ultimate CF SLX 8.0 DI2 rim brake version.
However, i am torn between a size S or size M.
I did a bike fitting last year for a used Cervelo R5 which is a size 56 ( the frame was a hand-me-down ) and i was advised to use a 80mm stem but due to aesthetic purposes, i used a 100mm stem instead + not slammed. I do feel overstretched at times but still manageable.
I figured that the R5 is probably too big for me.
And as I compared both bikes' geometry;
Below are my findings, i might be wrong as i am really not good at reach / stack and stuffs so please correct me if i am going the wrong direction.
the R5's reach + recommended stem length 80 mm = 467 mm
the R5's reach + the 100 mm stem i used = 487 mm
the size M's Ultimate's reach + the integrated stem length 100mm that comes with it = 491 mm
the size S's Ultimate's reach + integrated stem length 90mm that comes with it = 475mm
Basic above, it would seems i will be even more stretched on the size M ultimate compared to the R5 with 100mm stem.
I've also punched in my numbers on the Canyon PPS and i was recommended a size M so i am pretty confused.
I am about 180-181cm tall with an inseam of 84cm
My saddle height at the moment is about 706mm from center off bb to center of saddle profile.
Let me know if i missed out anything.
Any input will be appreciated !
Thank you !
Reach without stack isn't as meaningful. The small will be better when it comes to reach, but maybe the bars will be to low. If the drop on the S (or the necessary spacers) suit you, go for it. A bikefitting is more reliable than Canyon's PPS.
