Helpful reply there. He says he already has centrelock. If he follows previous advice he will save weight, it won't cost that much, and you don't really need that much rear braking power anyway (if you really need 160 rears you probably need 180 fronts - my B4s work just fine with 160/140).Cloxxki said:If you want to save weight, just stay away from centrelock, I'd say. I can see how a 140mm setup would even end up heavier. Why bother, for that huge investment, tiny possible shaving, and loss of brake power?
