Ready for aggressive mountain bike rides, the Shimano XT M8000 model features an aluminium lever and caliper construction. This makes it more than capable of handling all the abuse from trailside obstacles and bumps from the rocky terrain. Shimano has also gone a step further by giving this MTB disc brake's lever an anodised finish. This means you'll benefit from an extra layer of durability and corrosion resistance as you weave between the mountain bike trails in all weather conditions. Adjustable MTB Disc Brake Designed for ease of use, this MTB disc brake is kitted out with an adjustable lever reach. This allows you to fine-tune the distance between your handlebar and the lever to perfectly match your hand size, riding style and terrain conditions. As a result, the Shimano XT M8100 Disc Brake is an excellent choice of upgrade for riders who want a more customised braking feel as they blast across the mountain bike trails. Technologies: 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-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 the handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences. Free Stroke: The distance from the initial lever position to pad contact point can be adjusted to suit any hand size, type of riding and individual rider preferences. Ice Technologies: The fade, which can occur to disc brake rotors and pads when braking on a long downhill ride, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium 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. Shimano has 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.

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 stabilise 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.
