The Shimano MT800 Centerlock Disc Rotor is a high-performance disc brake rotor designed for use with Shimano mountain bike disc brake systems. This rotor features a centerlock mounting system that makes installation and removal quick and easy.

The MT800 rotor is made of durable stainless steel and features a two-piece design that helps to reduce weight and improve heat dissipation. The rotor also has a special Ice-Tech construction that includes a layer of aluminum sandwiched between two layers of stainless steel. This helps to improve heat dissipation and reduce brake fade, for consistent and reliable braking performance even during long descents.
