Shimano SM-RT800 Center Lock Brake Rotor for Ultegra

Shimano SM-RT800 Center Lock brake rotor for Ultegra - the Ultimate in Heat Dissipation

The shimano SM-RT800 brake rotor impresses with Ice Tech FREEZA, an absolutely superior technology for optimal heat dissipation and dirt repulsion. Two layers of stainless steel enclose an aluminium core, making three parts total. The SM-RT800 was developed especially for the Ultegra BR-R8070, but is also compatible with other flat mount brakes.

Technology:

FREEZA Ice Tech
Ice Tech FREEZA brake rotors show even less fading due to 40° C less heat development compared to SM-RT98. The three-layer sandwich construction consists of stainless steel flanks and an aluminium core with integrated cooling fins. The two-part structure with the aluminium spider dissipates the heat well. The dirt-repellent design extends the service life of the rotor and pads. A real eye-catcher is the sporty, aggressive high-tech design.
