Canyon CF ultimate SL7 di2 (105) on Wahoo Kickr Core

Hi everybody,

I’m having trouble mounting my canyon bike on my hometrainer. Once installed, the cassette is stuck and won’t turn. There’s also a problem with the fork tips who are in contact with the hometrainer.

When fitting the cassette to the wahoo kickr core, I left all the spacers in the same place on the hometrainer (there are 5 or 6 of them).

In short, do you think there’s a compatibility problem between my bike and the hometrainer? If not, what would be the best solution (simplicity), install a new cassette on the HT and leave the bike’s native cassette in place with its spacers in the right order?

Technical details of the bike and HT :

A) Hometrainer : Wahoo Kickr Core (2021 version)

B) Bike : Ultimate CF SL 7 Di2
Front derailleur : Shimano 105 Di2 RD-R7150 12s
Rear derailleur: Shimano 105 Di2 FD-R7150
Cassette: Shimano 105 R7100, 12-speed, 11-34T; Number of sprockets: 12, Range: 11-34
Thru Axle : Axle size: 12x100 mm & Axle size: 12x142 mm

Many thanks,

There should be a 142mm left side adapter, and the drive side spin cap installed on the trainer (parts 4 and 7 in this document): https://support.wahoofitness.com/hc/en-us/articles/360018850859-Updated-KICKR-CORE-thru-axle-adapter-installation

Note that they changed the design of the adapters so you should understand which version you have.

There should be no spacer underneath the cassette.

Supposedly the disc brake version of the Canyon Ultimate is compatible but the rim brake version is not: https://support.wahoofitness.com/hc/en-us/articles/4407140853650-Bicycle-Frame-Compatibility-KICKR

Does your bike have rim brakes or disc?

Hi @Pierre-Camille_Dauss welcome to Zwift forums.

Shuj at Zwift HQ here. Canyon also offers information on their support site.

As others have noted - Wahoo has made some modifications to some of their KICKR trainer axle adapter ends which may or may not help improve interference with your specific frame. It’s worth looking at the adapters you have to identify which is on your trainer.
