Is the brake against my trainer problematic?

Stevo 19 days ago

Just moved my new road bike (Tarmac SL8) to my Tacx Neo 2T with a Zwift Cog. Felt like a tight squeeze, got it on. It runs smooth and quiet. However there is NO space between the brake and the trainer body. Is this problematic? With the pressure against the brake cause problems over time?

Yes, it is problem, you can crack your bike frame. use different bike on the Neo or remove the rear brake caliper. or replace the Neo for a Kickr , these are the solutions.

I had to use the 2.7mm axle spacer for my setup to fix this. Not sure if you are already using the spacer. Here's the link to the Garmin support article;

if you move the bike with standing sprint, the frame can rotate (get twisted) a bit, so even with spacer(s) you need minimum 3mm between brake caliper and Neo. and too much spacers are also not good for the chainstay/frame. but it is up to you, i have seen cracked frames on Neo due to this problem. (if you never do sprints or never stand up and just pedal very smoothly in sitting position, then it is ok)

I used the 2.8mm spacer and works well. seems to be spaced off brake and doesnt seem to but flex or tension on frame. I hope it's no risk for the frame.

I'm glad it fixed your situation. I've had mine set up for over 2 years with the spacer, no issues.

But like the guy said above, this will increase the axle width the frame will have to accommodate.
