I just broke my 2nd Rotor crank set in 7 yrs. I am over it. I am using 11 speed Etap will the 12 speed crank set work with it?. I can get a good price with Quarq PM option.

Crickets?. I thought this is the place for all the tech gurus?

Seems unlikely since the AXS chainrings have narrower teeth/different sized rollers than the 11 speed variety (new chain and all).

Any idea why they broke? Do you wipe sweat off? Ride on the trainer a lot?

You canNOT use the 12sp crank Cuz they are attached to the rings.
