I was excited to mount these rotors, until I noticed the spider and rivets are too long and interfere with the brake pad levers on BB-7 road brakes. I tried respacing the calipers with some washers, but not enough of the rotor brake surface was exposed. I bought some cheaper CenterLock rotors that don't have the same length spiders, and they work fine with Avid BB-7 road calipers. Too bad - these are really well made, and I'll sell them on Ebay second-hand as they are used and cannot be returned.
I love these discs. I replaced the Stock Tektros on my Trek FXS6. I put Shimano resin pads on too. I'll be further upgrading to Shimano XT calipers and levers. It'll be a sweet set up! .
As is true for other XT components, this rotor defines the intersection of superior performance at a reasonable cost. Excellent stopping power in all conditions. The only caveat is that one must be careful when truing these rotors - they can be irrevocably damaged if bent too far.
