Shimano RT81 Ice Tech CL Disc Rotor

Shimano's XT/Saint RT81 Ice-Tech CL Disc Rotor delivers excellent stopping performance for powerful and consistent braking in all conditions. Manufactured from a 3-layer sandwich construction of stainless steel and aluminium, the Shimano XT/Saint RT81 Ice-Tech CL Disc Rotor manages heat effectively and consistently.

Enhanced Braking Performance
The 3-layer sandwich construction allows heat build-up to radiate quickly through the aluminium core to achieve a drop in surface temperature of around 50°C. When coupled with Shimano's Ice-Tech pads the surface temperatures can drop from around 400°C to 300°C, which provides a big boost overall performance.
