Nail the toughest lines! Shimano's SLX Disc Brakes are equipped with features to maximize every ride. They use two oversize ceramic pistons for serious power with modulation. Ceramic pistons and the use of finned ICE-Tech brake pads dissipate heat better, so you get confident speed control with stable braking and no fade or squealing on long descents. The levers feature Servo-Wave technology for quicker engagement, more pad clearance and less free stroke, perfect for aggressive enduro/all-mountain riding. The whole system also features improved ergonomics, quick and easy one-way bleeding, direct line routing, tool-free reach adjust, and is compatible with I-spec shifter/brake integration brackets. With its impressive blend of power, ergonomics, and weight, you just can't beat SLX.
