We’ve put my brother’s Canyon Inflite on my “old” Kickr Core (2020?). Unfortunately, he cannot shift in the smallest cogs (biggest gears).
The bike has a 142mm thru axle and comes with a pair of (OEM?) DT Swiss wheels with a SRAM 11-36 11-speed cassette on it. I put the 11-28 SunRace 11-speeed cassette that came with my Kickr 5 on the Core. Now, The spacing from the frame/trainer contact point to the smallest cog is smaller, the cassette further out when the bike is on the trainer compared to the rear wheel. As a result, he can’t use the 11 tooth cog and the next up is also noisy. The thru-axle adapters seem to be installed correctly and the bike basically mounted itself without undue force and with no lateral play.
I will ask my brother to take a couple of pictures (there’s not much to see though), but does any of you have had a similar issue? Does anyone have an idea how to fix this? Adjusting the rear derailleur every time he puts the bike on the trainer or the rear wheel back is a no-go.
I only ever had my road bike with a classic 130mm QR and a 10-speed cassette on the Core and never had to adjust anything when moving it from road to trainer use. My impression is that the spacing on the DT hub is weird (which is funny as I also have DT hubs, but they are conventional 350s, no OEM stuff).
