I am going to be building up a new bike and will be using XTR brake calipers. I'm building new wheels too so I have to decide if I want to use the centerlock rotors or standard 6 bolt rotors. Once you figure in the weights there is really no difference (hubs+rotors), is there a performance advantage to the centerlocks, are they less likely to warp, do they dissipate heat better, etc? BTW I will be using DT 240s hubs. Thanks in advance for the feedback.
