Shimano BR-RS811 Direct Mount Rim Brake with R55C4 for Carbon Rims

The Shimano BR-RS811 Direct Mount Rim Brake with Brake Pads for Carbon

The BR-RS811 rear wheel rim brake from Shimano, which is mounted directly on the chainstays in the bottom bracket area, is also available with special pads for carbon rims. The double-joint model has neutral Shimano branding, but is Ultegra-level. A direct mount favours the aerodynamics of the wheel and looks visually coherent, especially since the brake pleases with its slim design. Added to this are the efficient, precision-controlled braking power and the optimal ratio of stiffness and weight. You can ride with BR-RS811 tyres up to 28 mm wide. Both the brake arms and the cartridge brake shoe mounts, which are of course angle-adjustable, are made of lightweight aluminium.
