I bought a wahoo kickr. We use 11 speed sram with XD drivers. I purchased an 11 speed Sunrace cassette to mount on the 11 speed shimano road cassette hub with a 1.8 mm spacer. All is good, except what I didn't know is that it appears that XD drivers space the cassette about 2 mm closer to the deraileur, so when ever I mount the mountain bike the deraileur needs to be adjusted inboard a few mm. Not a big deal, but I have my kids and myself use this setup, and if I don't remember, or get the deraileur adjustment back just right we have shifting trouble on the trail or at a race. I was hoping to be able to grab a mountain bike, take the wheel off and drop it on the trainer, then just throw the wheel back on. I thought about adding two spacers to the cassette, but then I can't get the cassette lock ring to thread on. Any suggestions?
