Shimano RT-CL800 Disc Rotor - External Spline Type 180mm
Shimano RT-CL800 Disc Rotor - External Spline Type 180mm Info
The Shimano RT-CL800 Disc Rotor is built for riders who demand consistent stopping power across long descents and variable terrain. The 180mm diameter provides strong, progressive braking force, while Shimano's Ice Freeza technology uses a finned aluminium cooling layer designed to dissipate heat more effectively than a standard steel rotor — keeping brake feel stable and fade to a minimum when the trail or road gets technical.
The external spline mount keeps installation straightforward on compatible Shimano freehubs and hubs, and the two-piece construction — steel braking surface bonded to an aluminium spider — reduces rotational weight without compromising durability. At 180mm, this rotor suits riders who want additional braking leverage, whether on a loaded gravel bike or a trail-oriented build.
