Shimano RT-CL800 160mm Center Lock Disc Brake Rotor | ICE TECHNOLOGIES FREEZA | Internal Lock Ring
Shimano RT-CL800 160mm Center Lock Disc Brake Rotor | ICE TECHNOLOGIES FREEZA
Premium braking performance with advanced cooling technology for road, gravel, mountain, and performance e-bike applications.
The Shimano RT-CL800 represents Shimano's latest generation of premium Center Lock disc brake rotors, engineered to deliver quieter braking, improved heat management, and consistent stopping performance during demanding rides. Whether you're tackling long alpine descents, aggressive gravel routes, or technical mountain bike trails, the RT-CL800 helps maintain confident braking when it matters most.
Built around Shimano's renowned ICE TECHNOLOGIES FREEZA cooling system, the rotor features an aluminum core sandwiched between stainless steel braking surfaces with integrated cooling fins that rapidly dissipate heat. Lower operating temperatures help reduce brake fade, extend pad life, and maintain predictable braking throughout prolonged descents.
A newly reinforced rotor arm design improves overall stiffness, reducing vibration and unwanted noise while delivering a more controlled braking feel. Despite its increased rigidity and cooling capability, the RT-CL800 maintains an impressively lightweight design for performance-focused riders.
This version is supplied as a 160mm Center Lock rotor and includes a Shimano Center Lock internal serration lock ring for installation on compatible hubs.
