have held up well
by Zurich

these are very nicely made and have held up well. they are thicker than the Shimano rotors. I would have given them 5-stars, but they do not come with lock rings and are a bit too pricey for what a wear item.

Lighter, but not quieter

Originally, I used an adapter on my 6-bolt rotors, which appeared to be warped out of the box, with no amount of bending would eliminate completely the occasional 'ching-ching-ching' of disc brake resonance. I upgraded to this in hope of eliminating this annoying noise, but it also rubs occasionally, and also appears slightly warped at exactly the same spot as the 6-bolt rotor rubbed. The rotor is stamped with a directional arrow that somehow during production causes a slight warp on the rotor. Not horrible, but sometimes annoying. The brakes function great, but sometimes I wish I'd chosen the rim brake option to this setup.

Centerlock is the bomb. These dissipate heat very well, now squeaks. What else could you ask for?

Quality Product
by Anonymous

This rotor is better quality, stronger, less likely to bend and lighter weight than the rotor that came on my bike.

Great center lock alternative to the more pricey

So I use a pair of these on a cyclocross training wheelset, and I sue a pair of the more expensive Sram XR rotors on my road wheelset. But despite the XR's being almost twice the cost of this model, I can not tell why these are "inferior" or the "lower end" model from SRAM. These seemed great, were a little less "heavy" looking with the more open black interior portion, and SIGNIFICANTLY cheaper than the road XR version. They do the job great, look fantastic, and don't cost a ridiculous amount per rotor.
