Shimano RT-MT800 XT Centrelock Disc Brake Rotor (160mm-Internal Serration)

RT-MT800 Shimano Deore XT Centrelock Disc Brake Rotor (160mm-Internal Serration)

XT disc brake rotors deliver powerful and consistent brake performance for all riding conditions. The ICE TECHNOLOGIES FREEZA rotor significantly reduces heat build-up in the brake system to ensure consistent high performance braking even on the steepest downhill stretches. SHIMANO's CENTER LOCK mounting system makes installing and removing rotors quick and easy thanks to the spine mount and lock ring design.

The Shimano RT-MT800 is a center lock brake rotor with Ice-Tech technology. This means that the sandwich composite consists of two stainless steel layers with an internal aluminium layer. This ensures excellent heat dissipation even on long descents and difficult trails. The RT-MT800 rotor is recommended for newer XT brakes, but is also compatible with other models.

Heat Dissipation Technology

The RT-MT800 rotor features Shimano’s advanced ICE TECHNOLOGIES FREEZA system designed to manage heat during prolonged braking. Its triple-layer sandwich construction combines stainless steel outer layers with an aluminium core that improves heat radiation and cooling efficiency.

This design helps reduce rotor surface temperatures significantly during heavy braking conditions, such as steep downhill riding. Lower temperatures help minimize brake fading, reduce noise, and improve braking consistency. The improved cooling performance also extends brake pad life while maintaining reliable stopping power on demanding trails.

Easy Operation / Usage

• Installation Method: Mount the rotor using the Center Lock spline system on compatible hubs

• Lockring Tightening: Secure the rotor using the internal serration lockring

• Maintenance: Periodically check lockring tightness and rotor condition

• Compatibility Check: Ensure compatibility with narrow-shape brake pads and Shimano brake systems
