Been using this trainer for about 6 months now and had some fitting problems with my two separate bikes.
Over the winter my nice bike, a 2019 TCR disc (with thru axel) was permanently fixed to the trainer and I had to loosen the rear brake caliper to allow the bike the slightest of clearance from the tacx black plastic casing.
Last week I swapped over and put my winter bike on the trainer, a 2016 (I think) Specialized Allez. Being rim braked, this bike doesn’t have the problem of the rear caliper fouling the trainer but the actual chainstay itself is now wedged in against the black plastic when everythings tightened up. Its not much but its definitely pushing against it.
I also have always had to position about 4mm of cardboard under the right hand side of the trainer, to get both bikes to actually sit upright and not lean to the right! I’ve checked the floor with a 1m spirit level and it’s pretty damn straight.
I’ve been meaning to post these issues for a while and ask if anyone else has had these problems.
