Shimano BR-M8120 / BL-M8100 XT Brake Lever And Post Mount Calliper Set

Powerful fully bled XT 4 pot hydraulic Servo Wave disc brake for more aggressive riding styles.

Technology

Free Stroke

The distance from initial lever position to pad contact point can be adjusted to suit any hand size, type of riding and individual rider preferences.

Servowave 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-rim contact so more of the lever stroke is used to apply greater braking power with improved control.

Reach Adjust

Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.

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.

• 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

With its wider adjustment range, I-Spec EV levers can be adjusted to the optimal position to match a wider range of riding styles (Enduro / XC / etc.), rider preferences and rider anatomies (hand and arm alignment).

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.

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. 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.

Ice Technologies piston in order to achieve optimized lightweight, high rigidity and heat dissipation. Oversized pistons transfer hydraulic power directly to the brake pad, and ceramic material is used to avoid heat transfer for constant stable braking, providing efficient stopping power transfer without loss.

Four piston

Disc brake system with the dual diameter opposed-piston caliper design has differently sized pistons in front and in the rear. The system adopts a power transfer system in which the disc brake rotor is pressed by the smaller sized piston at the entrance of the disc brake rotor intake and also by the more powerful larger sized piston at the back. This prevents the wobbling motion of the disc brake rotor and reduces noises significantly.

The 4-piston caliper also allows a wider contact area for the disc brake rotor while keeping the size compact, and the efficient location of pads is adjusted as necessary to stabilize the pressure. In combination use with the Servowave lever it provides an incredible 50% more stopping power than the previous model. The advanced Saint / Zee disc brake system, which adjusts to accommodate the different braking styles of different riders, offers stable braking power and excellent modulation.
