I got a new Chisel a few months back and it’s shimano with the resin pads. 180 front and 160 rear. I have heard the resin pads are not great so new rotors and metallic pads would be an improvement. If going with new rotors should I up the size? 200/180? Or 180/180? I have center lock and I was gonna go with XT or SLX rotors which would be a little lighter than what’s on there now. I ride mainly XC with some fast sections here and there. Stopping power of the current brakes are adequate. I do plan on going with lighter and more adjustable XT or SLX brake levers. So rotors, keep 180/160 size or go up to 180/180 or 200/180. Metallic pads?
