Shimano Deore XT BL-M8100 + BR-M8100 J-Kit I-Spec EV disc brake set
Being a part of the updated Deore XT M8100 groupset, the new Shimano brake system set a new standard in terms of modulability and performance. Thanks to the new I-Spec EV system, the lever has 2 support points, which guarantees superior stability, while the main feature allows lateral and angular adjustment of the shifter with a single screw mounting option, thus keeping the handlebar in perfect order.
The design of the lever follows the lines of the XTR and offers Reach and Free Stroke adjustments for custom braking. Servo Wave technology also provides faster response and unparalleled braking power.

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.
One Way Bleeding
“One Way Bleeding” was developed for quick and easy prevention of air in Shimano's hydraulic system. They've streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.
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.
Lever configuration
- Right lever: rear brake (hose length: 1700 mm).
- Left lever: front brake (hose length: 1000 mm).
Brake kit includes: hoses, fluid and Shimano pads.
