Shimano pair of disc brakes Deore XT BL-M8100 + BR-M8100 XC Race I-Spec EV 2019
The new Shimano brakes are part of the updated Deore XT M8100 group and represent a new standard in terms of modulation and performance. Thanks to the new I-Spec EV system, the lever has 2 support points, which guarantees superior stability, while the main function allows a lateral and angular adjustment of the shift control that is fixed with a single screw, thus keeping the handlebar in perfect order. The lever design echoes the lines of the XTR and offers Reach and Free Stroke adjustment for custom braking. Thanks to the Servo Wave technology, faster engagement and unparalleled braking power are also achieved.

TECHNOLOGIES
Ice Technologies
The incorrect configuration of the disc brake rotor and pads when braking on a long descent, for example, has a negative impact on brake performance. Shimano has adopted Ice Technologies disc brake rotor and pads to achieve cooling technology that ensures consistent performance. The coated disc brake rotor blade, equipped with a 3-layer sandwich structure in stainless steel, aluminum and stainless steel, ensures better heat dispersion (from 400°C to 300°C surface temperature). The cooling fin for the pad ensures less wear, less noise, less loss of efficiency and greater lightness.
One Way Bleeding
The "One Way Bleeding" function has been developed to ensure the quick and easy prevention of air ingress in Shimano hydraulic systems. They optimized the entire oil circuit in the system to prevent air bubbles from being present inside it. The unidirectional oil circuit, together with a funnel instrument with mineral oil, ensures an easy and clean purge system.
I-Spec EV
The I-Spec EV creates a clean, optimised cockpit that enables greater concentration and comfort for a wide range of cyclists.
Advantages and benefits
The wider adjustment range allows cyclists of the most varied styles, preferences and body types to find the optimal lever position and control.
Ergonomic design, faster access to the lever and smooth operation improve driving comfort and concentration.
The I-Spec EV increases the rigidity of the brake lever by moving the clamp inwards to create an additional point of contact between the handlebar and the lever. This additional support greatly increases bike control and brake response, maintaining a gap between the strap and the support point for other accessories to be mounted on the handlebar.
Servo Wave Action
When the Servowave brake lever is operated, the initial recall of the cable is faster, so a small travel of the lever is sufficient to bring the pads into contact with the brake disc. Then the power multiplication factor increases rapidly on contact, so greater lever travel is used to apply more force with higher levels of braking control.
