I am building-up a new set of race wheels that will have IS 6 hole mount hubs for the rotors instead of the XTR centerlocks that I have been using on my current wheels. I'm looking for some suggestions for a good light 160mm rotor that will be compatible with my XTR 970 brakes. I'd love to find something reasonably light and not too expensive. I realize that this may not be possible so I am also looking for any reasonable rotor that is compatible with XTR brakes and doesn't squeal. I am using the XTR resin brake pads. Any suggestions would be greatly appreciated.
