Is anyone using this combination/have experience or opinion on it...think it could be enough {with ice tech rotors}...interested to hear
My wife has uses 140 rear and 160 front rotors, currently with XTR race brakes, but previously Avid and Hope ones. She is pretty quick, but also light weight and has had no problems with that setup. Were we live is fairly flat, but the brakes have been fine at occasional away days at Afan etc. She bought a bike a couple of years ago with the 140mm rear rotor and has never felt the need to change it, although the bike and brakes have changed in the time! It doesn't actually save that much weight.
Also running 160/140 XTR race brakes, not on Ice Tech rotors. Fine for XC use, would probably go 160/160 for Enduro racing, but no real logic to that, Steve Peat won the world champs on 160/140 after all!
