XT/Ultegra level RT-CL800 Ice Tech rotors provide consistent braking performance through energy control. This design reduces heat-related rotor deformation for quiet, consistent, and prolonged braking.
The rotors use a revolutionary stainless steel/alloy 3-layer sandwich construction that manages heat while riding. The clad steel/alloy/steel construction allows heat generated from braking to radiate quickly through the aluminium core, achieving surface temperature drops of around 50°C. When used with Ice Tech pads, surface temperatures can drop from around 400°C to 300°C, providing great improvements in performance.
Freeza rotors allow the alloy core to extend out from the braking surface as a fin to provide added cooling. Ice Tech rotors achieve long pad life, less noise, and less fade due to improved heat dispersion. The rotors are durable, lightweight, and rigid, using the proven Shimano Center Lock system for increased strength, security, and easy set-up. A precision cut braking surface improves pad clearing in muddy conditions while aiding cooling under high load. The large alloy spider provides a highly rigid and lightweight support for the rotor surface, while the super polished braking surface gives excellent braking performance.
An updated rotor arm shape and ICE TECHNOLOGIES FREEZA cooling maintain braking performance on long, steep descents without adding unnecessary weight.
Features:
- ICE TECHNOLOGIES FREEZA: Radiator fin design improves cooling efficiency during prolonged or repeated braking.
- Reduced Brake Noise: Improved rotor stability helps minimise vibration for quieter operation on long descents.
- Reinforced Arm Design: New arm shape increases stiffness, contributing to quieter, more controlled braking.
- Lightweight Construction: Cooling performance is achieved without sacrificing rotor weight.
