Offering exceptional all-condition braking, easy maintenance and hassle-free brake bleeding, this Ultegra caliper is durable, stylish and powerful.To the delight of riders and mechanics alike, the new Ultegra BR-R8170 caliper delivers enhanced modulation, a quieter brake system, and an easier than ever bleed process. The Ultegra R8170 disc brake caliper brings a new level of control to the road cycling world with enhanced modulation and a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain. ICE TechnologiesThe fade, which can occur to the 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, aluminium 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. One Way Bleeding“ONE WAY BLEEDING” was developed for quick and easy prevention of air in our hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system.

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.
