Meet the all-new Lewis AX 4-Piston Disc Brakes, the most advanced Lewis system to date. Engineered for MTB, e-MTB, and e-MX riders who demand absolute precision, control, and power on every trail.

Machined from 7075 T6 aluminum, Lewis AX 4-Piston Disc Brakes employ a 4-piston mono-block caliper (with 2×18 mm + 2×20 mm pistons) to deliver ultra-consistent braking force, while independent cooling fins keep performance steady when the heat ramps up.

Tool-free Reach and Bite Point adjustments, plus a worm-gear leverage ratio dial, let you tune lever feel in seconds. A revised and improved anti-oil-loss system adds hassle-free convenience for internally routed setups.

Tipping the scales at just 311g per brake (without hose and pads), Lewis AX 4-Piston Disc Brakes stay impressively light yet brutally capable. Built for riders who expect pinpoint accuracy and enduring power on every descent.
