Shimano Saint M820-B Pre-Bled Rear Disc Brake with Metal Pad, Black / Gold

Shimano Saint M820 Disc Brakes are every bit as good as they were expected to be. The new brakes use Ice Technologies and Shimano's new lever shape to boost braking power to absurd levels without sacrificing control. Shimano retains the dual-diameter, quad-piston design for maximum modulation. The pistons are now ceramic to limit heat build up. The new Saint pads have fins on both the inside and outside to help channel air into the caliper. Less obviously, a new longer banjo acts as a heat sink to cool fluid as it moves through the system. The new lever follows the the new XTR shape, offering less weight and less fatigue thanks to the new pivot location. Shimano's Free Stroke, external reach adjustment, and Servo Wave are all included and help boost power and adjustability.
