Shimano XTR BR-M975 / RT97 S Front 160mm Rotor

Shimano's BR-M975 has an opposed two-piston design while reducing weight: The one-piece design is more compact and very stiff which results in a precise and efficient disc brake design. The titanium back plate on the new XTR brake pads are 12 grams lighter than current steel pads. Durability in the pad is also improved by 50%. Uses international standard calipers. Rotor and brake caliper only.
