SHIMANO’s new brake systems deliver refined control, lighter lever action, and unmatched stopping power, giving riders the confidence to brake later and ride harder. With improved modulation across both 2-piston and 4-piston caliper options, these brakes offer a more intuitive feel at the lever, allowing for precise adjustments in technical terrain.
