Building off the smashing success of Shimano's XT BR M785B Disc Brakes, the Shimano XT BL M8000 Disc Brakes offer enhanced ergonomics with their sleek integrated master cylinder and simple integration with I Spec II shift levers. Not only does this improved design shave precious grams, but it also frees up valuable real estate along the handlebars, which is always a positive with the ubiquitous use of dropper posts on modern trail bikes. Sero Wave technology delivers reliable stopping performance across widely variable trail conditions and riding disciplines. This technology improves brake engagement by closing quickly upon first squeeze, ramping up power after initial engagement for improved bite. 22mm ceramic pistons inspire riders to push their limits with gobs of stopping power at a moment's notice. Shimano's Radiator Pads disperse heat on shuttle runs and lift accessed downhills, preventing dreaded brake fade on lengthy descents. Tool free reach adjustment dials in a custom feel for precise trigger actuation. The Shimano XT BL M8000 Disc Brakes come with everything needed for installation. This brake kit works with Shimano's XT and XT Ice Tech Rotors for reliable stopping performance in all conditions. Hinged, split clamps allow for easy mounting. The pre bled levercaliperhose assembly is ready for installation on your favorite trail bike.
