Shimano XTR BR-M9020 Trail Disc Brake Technical terrain requires complete confidence in your equipment. At high speeds, nothing instills more confidence than knowing your brakes are ready and able to deliver unparalleled control and reliability in any situation. Shimano XTR brakes are arguably the best performing hydraulic disc brakes on the market, offered in two flavors: Trail and Race. The Race model is the no-frills, lightweight version while this Trail model offers a more adjustability and trail-tuned performance with only a minor weight penalty. To provide highly adjustable, high-powered braking performance with no compromise, Shimano designed the XTR Trail M9020 hydraulic disc brakes. The integration of Servo-Wave brake-boosting technology into an XTR M9020 Trail brake generates gobs of lightweight stopping power (125 percent of the previous XTR benchmark, to be exact) that can be precisely rolled on and off with single-finger effort-giving you a better grip on the bar and ultimately better control of your ride. Shimano was the first in the industry with full ceramic caliper pistons, but that's not all the set XTR braking performance apart from the rest. The new XTR Trail M9020 brakes also feature a newly redesigned carbon/alloy lever for improved ergonomics, insulated pistons and radiator-fin-backed brake pads to shed performance-sapping heat, allowing the XTR M9020 brakes to maintain cool, quiet performance under extreme braking. These brakes not only save weight, but stay cool, delivering excellent, predictable brake perfromance.
