consistent braking performance in all riding conditions. Shimano's Centerlock mounting system makes installing and removing disc brake rotors quick and easy, thanks to the spline mount and lock ring design.

incorporates ICE cooling technology and a mud shedding rotor blade design to keep the rotor cooler and cleaner for optimal braking performance in all conditions. Shimano Deore XT rotors are constructed using ...

and consistent braking control for any terrain. FREEZA Technology focuses on decreasing disc brake rotor heat deformation, the result is quieter brake performance without sacrificing weight or heat dissipation.

Brake pads, significantly reduce heat build-up in the brake system. This also reduces fading, ensuring consistent high performance. It also results in longer pad life and quieter braking.
