Why We Like The Shimano RT-CL800 Rotor

Built for a quiet and consistent braking performance, the Shimano RT-CL800 Rotor is ideal for long, steep descents where trusting our brakes is key. It features Ice Technologies with Freeza rotor construction to allow for a longer pad life, less noise, and long-lasting durability. The RT-CL800 rotor is part of the Shimano GRX 11-speed groupset and features a center lock system to allow for the easiest possible installation with a lock ring and spline mount.

They do their job

I've used it several times

They look really cool, and the bike stopped. What more can you ask for?
