Shimano RT-CL800 Disc Rotor - Internal Spline Type
Shimano RT-CL800 Disc Rotor - Internal Spline Type Info
The Shimano RT-CL800 Disc Rotor is built for riders who demand consistent stopping power across long, punishing descents and mixed-surface riding. Designed to run silently and dissipate heat efficiently, it uses Shimano's Ice Freeza Technology — a finned aluminium clamp ring construction intended to draw heat away from the braking surface and reduce fade on extended technical sections.
Available in 140mm and 160mm diameters, the RT-CL800 fits via an internal spline mount — the same standard used across Shimano's current road and gravel groupset lineup. Whether you're running a dedicated gravel setup or a road disc build, this rotor slots in cleanly and works with the braking character you'd expect from the GRX series.
