The ultimate in mountain bike braking, the Shimano XTR RT-RT900 disc is compact, lightweight and dissipates heat quickly thanks to Freeza technology. It features an aluminum layer sandwiched between two pieces of stainless steel that extends under the brake track to improve rotor cooling. The Centerlock mounting system allows for quick and easy installation and removal of the rotors with the spine bracket and locking ring.
