Shimano SM-RT800 Center Lock brake rotor for Ultegra - the maximum in heat dissipation
The Shimano SM-RT800 brake rotor inspires with Ice Tech FREEZA, an absolutely superior technology for optimal heat dissipation and dirt repulsion. It is built in three parts: Two layers of stainless steel enclose an aluminium core. SM-RT800 was developed especially for the Ultegra BR-R8070, but is also compatible with other flat mount brakes.

Ice Tech FREEZA rotors show even less fading due to 40°C less heat generation in comparison to SM-RT98. The three layer sandwich structure consists of stainless steel with an aluminium core and integrated cooling fins. The two-piece structure with aluminium support effectively conducts the heat away. The dirt-repellent design extends the durability of rotor and pads. The sporty aggressive high-tech design is a real eye-catcher.
