Shimano used a two-piece construction for their RT76 rotor. The center section is made out of aluminum, while the braking surface is stainless steel. The two piece design helps reduce heat build up and resists warping, ensuring a long life of trouble free breaking.
Shimano RT76 rotors are XT level and the perfect match for Shimano Deore XT M785-B Disc Brakes.
These are great brake rotors. Nice and quiet with lots of stopping power.
Great stopping power, no notice of fade when combined with the XT IceTech brakes.
