Shimano Deore XT 6-Bolt Ice-Tech Rotor (160mm)
Shimano's Deore XT Ice-Tech rotors utilize the industry standard 6-bolt mounting system for secure mounting. These rotors use an aluminum core with steel outer plates to better control the temperature of the braking surface. This means quieter braking and, more importantly, less fade on long downhills and improved pad life. The various sizes give you total freedom of choice over the delicate balance of power versus weight.
6-bolt brake rotors are the most common brake rotor attachemnt. They require six bolts to be torqued in sequence to achive optimum performance.
