Shimano RT-CL800 180mm Center Lock Disc Brake Rotor | ICE TECHNOLOGIES FREEZA | External Lock Ring
Shimano RT-CL800 180mm Center Lock Disc Brake Rotor | ICE TECHNOLOGIES FREEZA
Premium braking performance with advanced cooling technology for mountain bikes, gravel bikes, e-bikes, and demanding all-terrain riding.
The Shimano RT-CL800 180mm Disc Brake Rotor is engineered for riders who demand powerful, consistent braking on long descents and technical terrain. As part of Shimano's premium Center Lock rotor lineup, the RT-CL800 combines exceptional heat management, quieter operation, and lightweight construction for confidence-inspiring performance in every ride.
Featuring ICE TECHNOLOGIES FREEZA, the rotor utilizes a stainless steel and aluminum sandwich construction with integrated cooling fins to rapidly dissipate heat. Lower operating temperatures reduce brake fade, improve pad longevity, and deliver more consistent braking performance during prolonged or repeated braking.
A newly reinforced rotor arm design increases overall stiffness while reducing heat-induced deformation and vibration. The result is smoother, quieter braking with improved modulation and control, especially on long descents where brake temperatures traditionally increase.
This version features a 180mm Center Lock rotor and includes a Shimano Center Lock external serration lock ring, making installation easy on hubs requiring an external lock ring.
