RACE PERFORMANCE!

The XTR group is the top end in the SHIMANO MTB portfolio. In these high-performance components is everything in it, what Shimano has to offer in technology and know-how - better does not go! Optimized for MTB racing, they shine with low weight and best performance. The best racers in the world rely on these parts.

The extra-stiff from a block cold-forged Mono Body caliper of the XTR disc brake BL-M9120 unfolds with its 4 Ice Tech ceramic pistons concentrated braking power, which can be ingeniously dosed by the SERVO WAVE brake lever BR-M9120 with short idle travel. Compared to the XTR M9000 version, this brake achieves 30% more braking power.
The 2-finger brake lever with its ergonomic and anti-slip design is tool-free adjustable in lever width (Reach Adjust). With I-SPEC EV, the shift lever can be integrated into the cockpit space-saving and tidy. In addition, it offers with Free Stroke Adjust the possibility to adjust the idle travel.

The optimal compromise of low weight and high performance using titanium components completes the overall package. The brake including brake lever and caliper weighs just about 770g.

TECHNOLOGIES

SERVOWAVE Action
The SERVOWAVE brake lever absorbs a lot of brake travel at the beginning of its movement, so that the pads can be guided to the brake disc with little lever travel. After the brake pad is in contact, the power transmission factor increases rapidly. The greater part of the lever travel is thus still available for increasing the braking force and for more targeted control.

FOUR PISTON
The disc brake system with double-diameter caliper design and counter-rotating pistons has different-sized pistons at the front and rear. The system incorporates a power transmission system in which the brake disc is pushed by the smaller piston at the entrance to the brake disc mount and also by the stronger, larger piston at the rear. This prevents the brake disc from vibrating and significantly reduces noise.
The four-piston caliper increases the contact area with the brake disc while its size remains compact. The position of the pads is precisely matched to stabilize the pressure. In addition, in combination with the SERVOWAVE brake lever, an incredible 50% more braking power is achieved than with the previous model. The advanced disc brake system can be adapted to the braking habits of the rider and produces a consistent, superbly controllable braking force.

I-SPEC EV
This mounting system offers the best possible accessibility and ergonomics of the gearshift, as well as a tidy cockpit. The mounting is directly on the I-SPEC EV compatible brake lever. the lateral adjustment range is 14mm. In the angle, the switch is adjustable by 60 °. A second contact point between brake lever and handlebars brings additional stiffness to the brake lever and thus increases the braking effect.

REACH ADJUST
The brake lever is equipped with a grip width adjustment. This allows the handle to adjust to the size of the rider's hand or riding style or personal preference.

FREE STROKE
The distance from the initial position of the lever to the contact point of the brake pads can be adjusted to the size of the rider's hand, as well as his riding style and personal preferences.

ICE-TECH brake piston
ICE TECHNOLOGY pistons for weight optimization, high stiffness and heat dissipation. Oversize pistons transfer hydraulic power directly to the brake pad. A ceramic material (XTR: Highly Insulated Plastic) is used to prevent heat transfer and provide consistent, safe braking performance. This provides efficient braking power transmission without losses.

ONE WAY BLEEDING
"ONE WAY BLEEDING" was developed to quickly and easily prevent air from being in the hydraulic system. We have optimized the brake fluid line path throughout the system to prevent air bubbles from becoming trapped in the system. The line path of the mineral oil in only one direction, together with the funnel for filling, allows clean, trouble-free bleeding.
