XT ice tech rotor

Keeps brakes nice and cool


Part works perfectly. Rotors are bedded in and performance is great.

203mm RT86 Ice Tech rotors

I upgraded my IBIS from 180mm Shimano RT66 rotors and was blown away by the grip and fade resistance of the RT86 rotors. Calipers and pads are identical but I no longer see any signs of fade on long descents. Don’t forget to get associated caliper mounts when buying, but otherwise I cannot recommend these enough. Shipped fast and arrived quickly.


 awesome product. Also, you guys rock I’ll deal with you from now on. Thank you very much.
