Shimano XTR Trail BL-M9120-L + BR-M9120 disc brake set

Shimano's XTR Trail lever pairs with the new 4-piston Trail caliper offering Rider Tuned stopping power for the ever more capable breed of modern mountain bikes. With tool-free reach adjust and Shimano's new I-Spec EV standard, the BL-M9120 lever continues to set the standard for mountain bike brakes.

Technologies

Ice Technologies

The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.

I-Spec EV

I-Spec EV creates a clean and action-optimized cockpit that provides greater focus and flexibility for a wider range of riders.

Benefits & Features

  • Wider adjustment range allows riders of various styles, preferences and body styles to adjust to the optimal position.
  • Ergonomic design, quicker lever access, and light operation enhance rider comfort and concentration. I-Spec EV increases brake lever rigidity by moving the brake clamp position inward to create an extra point of contact between the bar and the lever. This additional bracing drastically increases bike control and braking engagement while maintaining space between the clamp and support point for other handlebar accessories.

Servo Wave Action

When you pull a Servowave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-disc contact so more of the lever stroke is used to apply greater braking power with improved control.
