Almost ready to order, was just mocking up a paint design.

I did hear back from my bike fitter - he recommended to keep the 54, so as to not reduce the stack too much.

Paraphrasing:

"If you want to go more aggressive, you're better off keeping the height in the front to keep the hip angle open at the top of the stroke for stability through the pelvis. Canyon's come stock with short stems, so it makes it feel like it's upright, so you can opt for a longer stem".

Might stick with the 54 then and opt for the 110mm stem length.

I bought the 105 di2 groupset (electronic parts only, without crankset, chain, cassette) from Yiwu Donglue Bicycle Parts for 550 EUR (after coupons) including tax and shipping (to Germany). I received genuine Shimano parts, everything works well including updating the parts to the newest software version. I completed it with a Magene PES 515 crankset, ZTTO full cnc cassette and KMC x12 waxed chain.
This setup was just over 900 EUR and for me is currently the best value for money I could get.

Hey Bassa80, how did you go with tracking with Yiwu? I just purchased a full Ultegra Di2 groupset, the tracking number they uploaded to Ali shows something completely different (already delivered to Dubai). I messaged them and they just said "the logistic company haven't given me the correct tracking number,please wait ". Cautiously optimistic.

Reporting back, might need to go for the 54 or look elsewhere...

Just got a reply re: seatpost length.

"44/49/52 use 300mm seatpost
54/56/58 use 380mm seatpost"
"52cm cannot use 380mm, the frame will be damaged"
"All seatposts must be inserted at least 100mm"

My current bike has a saddle height of 698mm from the BB, and from BB to saddle rails of approx 670mm. The Ultimate has a seat tube length of 494mm, so that's approx 176mm seat tube exposed. This is also with 172.5mm cranks, which I wanted to change to 165mm.

The X68 in 52 has a 456mm seat tube. To get the same saddle height for same leg extension, I'd need the same BB to saddle dimensions - so approx 214mm seat tube exposed (670 - 456). With the change to 165mm cranks, this would increase to 221.5mm. With minimum insertion of 100mm, I'd need the 380mm seat tube, which apparently will damage the frame (hard to see how, given the 54 seat tube length is only 17mm more - maybe the seat tubes are slightly different dimension?)

Just read through this entire thread - I'm looking to get a new bike, and might roll the dice on this one.

Currently ride a Canyon Ultimate in size small, any recommendations on size for the X68? I'm 174cm, 78.5cm inseam, running 90mm stem on the Canyon. I did get a bike fit for the Canyon, but wanting something a bit more aggressive now - my saddle is pushed as far forward as possible on the Canyon. Size 54 still the way to go with 90mm stem? Or size down to 52 and increase stem length?


This would be my first bike build, so somewhat nervous about that too. Guess I could always take it to a local mechanic if/when I get stuck. Will be installing full Ultegra Di2 on it to start.
