I’m about to order some new rotors and I’m dithering between 160mm and 180mm, the pertinent details are: I’m 65kg with gear on, my bike is a 140mm full sus weighing 11kg, and I have Formula R1 brakes working well. I currently have 160mm rotors which stop me perfectly well, but I’ve only been riding XC where there is little call for repeated braking so fade doesn’t come into play, and I’m going to be getting into some more brake taxing riding. The new rotors will be floating to try and help dissipate the heat. So what would STW suggest is the rotor size for me?
Cheers
