Shimano XTR BR-M9120 4-Piston Disc Brakes, BR-M9120 4-piston callipers and BL-M9120 levers, full set (front & rear). Brakes are assembled with hoses, are pre-bled & include your choice of N04A Metal ICE or N03A Resin ICE pads.

Shimano's XTR M9120 callipers feature a MONO-BODY design which is machined from a single cold forged block to maximize rigidity which is then fitted with four ceramic pistons for immense stopping power. Paired with the enduro focused BL-M9120 levers with tool-free reach adjust and SHIMANO's new I-spec EV standard, the entire set continues to define the standard for mountain bike brakes.

  • Ultimate performance, response & brake modulation
    • High braking force with reduced input force at your fingertips. Very linear response, stroke, and 30% quicker response compared to previous generation M9000 brakes.
  • Increased braking power
    • 10% more braking power (vs. M9020)
      • 4 piston low-profile design
  • Banjo type connection
  • SERVOWAVE ACTION brake levers
    • Initial pad travel is fast¬†enabling quicker contact with the rotor.
    • Power then¬†increases rapidly, so more of the lever stroke is used to apply greater braking power with improved control.
    • Faster lever rebound for improved rider concentration
    • Updated lever shape
  • High rigidity
    • 8% stiffer than M9000 even under high temp conditions
  • Quicker brake engagement with shorter free stroke
  • Free stroke adjust allows for fine tuning of lever movement vs. initial pad contact point.
  • Easy, quick and clean installation and maintenance
    • One way and funnel bleeding utilizes a new, more convenient bleeding nipple position.
