The SHIMANO BR-M8220/BL-M8200 XT 4 POT BLED SYSTEM delivers race-proven braking performance for demanding enduro and trail riding. Built on Shimano's Servo-Wave technology, these hydraulic disc brakes feature a dual-diameter 4-piston design that balances raw stopping power with precise modulation. The short-stroke mechanism with SIL-TEC roller engagement provides immediate response and smooth power delivery, while free-stroke adjustment lets you fine-tune feel on the fly. Supplied without rotors or adapters, you're free to spec Ice Tech Center Lock rotors in 160, 180, or 203mm to match your setup. Lightweight forged construction and a reinforced lever contact point maximize rigidity without compromising weight savings—engineered for aggressive riding where control matters most.
