Riding with complete confidence in your brakes lets you go faster. With Shimano's Deore XT discs you'll be able to hold your speed until the last second in any situation. The mono-body caliper design makes this brake super light and extremely rigid. Cooling fins attached to the pads combat the dreaded fade on long downhills and actually make the pads last longer. The 2-finger Servo-Wave levers create quicker brake engagement without reducing pad clearance at the caliper. They also feature both adjustable reach and free-stroke so you can dial them in to your hand size and the whole package has clean cable routing and is super compact thanks to the radial master cylinder. And should you ever need to bleed them, Shimano's one-way system is a snap.
