RT-CL800 Rotor - Centerlock

What Our Gearhead® Experts Are Saying:

"I ride these rotors on my gravel setup and they’ve made a big difference on long descents. Braking is super quiet, even when it’s wet, and the Ice Tech Freeza design keeps them from overheating. Install was quick with the centerlock, and they’ve stayed perfectly true over dozens of rides."

Big climbs deserve confident descents, and that’s exactly what we get with the Shimano RT-CL800 Rotor. Designed to pair with Shimano’s GRX 11-speed groupset, this rotor delivers smooth, fade-free braking on everything from backroad passes to fast gravel descents. Whether we're pushing the pace or just trying to keep things under control, this rotor offers quiet, consistent power.

With Ice Technologies and Freeza construction, the RT-CL800 effectively dissipates heat, extending pad life and reducing noise. A robust aluminum arm adds stiffness for better modulation, and the centerlock design makes installation fast and secure. Available in both 140mm and 160mm diameters, it offers a tuned braking feel no matter your frame clearance or riding style.
