SHIMANO XTR M9120 J-Kit Disc Brake Kit

The SHIMANO XTR lever combines with the new XTR 4-piston caliper, offering optimized braking power for increasingly demanding riding situations with tool-free reach adjustment. The XTR M9120 4-piston caliper features a MONO-BODY design machined from a single cold-forged block to maximize rigidity, and four ceramic pistons for perfect braking power, suitable for all riding styles.

The faster rebound between actions allows the driver to stay focused
Higher braking force with reduced fingertip effort, very linear response. Braking power, stroke and return reduced by 30% compared to the M9000 model.
10% more braking power (compared to the M9020)
8% more rigid than the M9000 model even in high temperature conditions
Banjo-type connection and internal cable routing
Tool-free range adjustment

J-KIT = "junction kit" : The kit comes with the hose already connected to the caliper, all you have to do is connect your lever to your hose by adjusting it to the correct length, also making it easier to route the hose internally for compatible frames.
