Picked up a Kickr yesterday and it was a struggle to get my Cervelo P3 attached to the trainer b/c of the orientation of the rear drop out being horizontal instead of vertical. I ended up partially removing the skewer and taking off the nut so that the rear derailer could slide by.
yes, this is difficult to manage. my advice would be:
take the quick release fully out of the kickr and place it on the ground right beside the unit
with your rear wheel off, hold the bike’s saddle with your left hand and kind of get the front wheel where it needs to be
with your right hand, pull the chain backwards away from the rear dropouts as you lower the rear end towards the kickr
wrap this chain you’ve pulled around the smallest cog on the kickr cassette
slide the rear dropouts onto the kickr
it’s actually pretty easy once you get used to it. you’ll always get your fingers a little dirty though. i can make a video of this, but this is also how i swap wheels when my bike is on the ground and not in a repair stand.
whoops! typo. corrected. put the chain on the smallest cog on the cassette! you get a little more slack when the wheel is in the smaller chainring, but i’ve been able to do it just fine in either.
My TT rig has horizontal dropouts and I never remove the QR to put it on or take it off the Kickr. Gear to small ring/smallest cog.
It takes a little time to figure out hand placement that works best, but I always put one hand on the saddle and with the other grab the chain and think it feels like pulling back on an archery bow when you’re about to launch an arrow. I keep my drivetrain pretty immaculate, but you may want to keep a rag handy.
I do miss the simple days with a vertical dropout bike when you don’t even have to touch the chain for this stuff
