Shimano RT-MT905 6-Bolt Rotor - 203mm Info
The Shimano RT-MT905 6-Bolt Rotor - 203mm is a top-tier disc brake rotor from Shimano's XTR-level component lineup, built for demanding mountain bike use where heat management and consistent stopping power are non-negotiable. Constructed with Shimano's Ice Technologies Freeza design, the rotor uses a three-layer clad aluminum alloy sandwich between two stainless steel braking surfaces — a configuration intended to dissipate heat faster than standard stainless rotors and keep brake fluid temperatures in check during extended descents.
At 203mm, this is a large-diameter rotor designed for front wheel applications on enduro, trail, and gravity-oriented riding where maximum braking leverage matters. The 6-bolt mounting interface is universally compatible with standard 6-bolt disc hubs, making it straightforward to fit across a wide range of builds.
