Shimano Ultegra/GRX RT-CL800 Disc Brake Rotor
Best premium upgrade for road and gravel riders seeking silent braking.
This rotor is the gold standard for riders who prioritize consistent, fade-free braking on long, technical descents. The two-piece design sheds heat remarkably well, though you are locked into a Centerlock-only ecosystem. It’s a reliable, set-it-and-forget-it upgrade that ensures your stopping power remains predictable regardless of how hard you ride.
