I currently have a set of Zipp 303s and would like to swap them between my road /gravel bike and my new TT bike. The Zipps currently have Shimano XT rotors as my bike has a GRX groupset. The new TT bike is going to have SRAM S-900 Aero HRD brakes so obviously the bike comes with SRAM rotors. Will I…

One point about swapping rotor brands, and it is more MTB side but if you’re running magura calipers their rotors are 2mm as standard so I try to stick with magura rotors.
