I have a Tarmac SL7 2022 with Thru-Axel and disc brakes. Mounted on my Tacx Neo using the
for 142mmI noticed i noticed that there is still a lot of play/movement between the frame/adapter( QR bolt) on the non drive side.
As i see it, the frame and the adapter kit are not really that compatible somehow.
I also used what oivindflaterud suggested, In the adapter kit indeed there is a white o ring that i used on the inside the frame on the non- drive side it will actually become stable but the brake hits the part on the Neo.
