SHIMANO BR-RS811｜Under-BB Mount Brake That Fits Beautifully into Aero Frames
Aesthetics that integrate with the frame, and reliable braking power.
The SHIMANO BR-RS811 is a direct-mount rear brake caliper designed for under-BB (bottom bracket) mounting.
Specifically designed for under-BB mounting, often found on aero road bikes and time trial bikes, it features a low-profile design that enhances integration with the frame. It achieves both aerodynamic performance and style while providing stable braking power.
Compatible with SHIMANO's SLR-EV technology, it offers light lever operation and high control. With an excellent balance of rigidity, weight, and braking power, it supports high performance in a wide range of situations, from racing to long rides.
It supports tires up to 28C, accommodating the wide tires that have become popular in recent years. This direct-mount brake brings out the performance of modern road bikes.
