Shimano Ultegra R8110 Road Brake Caliper - Direct Mount - Rear

The slim SHIMANO Ultegra BR-RS811 Direct Mount brake caliper impresses with a controlled and reliable braking effect. With clear feedback, the rim brake can be excellently dosed on long descents and before sharp bends. Here, the compact design in chic anthracite plays off the advantages with a balanced ratio of stiffness and weight. The powerful brake is attached to the mounting points under the bottom bracket of your Direct Mount road bike frame.
