Clarks React-2 Piston Hydraulic Brakes 180/160mm

The CRS C4 is a 4 piston hydraulic disc brake that provides the rider with a competition level brake set, featuring full adjustment and modulation. Each caliper has 4 x 16mm stainless steel self-adjusting pistons with machined piston heads for reduced friction operation.

With heat dissipation features designed into the single piece CNC caliper, keeping braking performance consistent and in turn help to reduce pad wear. Lightweight 2 finger brake levers with ergonomic vented lever blades, offer controlled, sensitive braking by using an 'on the fly' lever reach adjustment screw. The C4 is supplied with aerospace grade aluminium floating rotors with stainless steel braking bands, hoses and mineral oil.
