Shimano BR-R451 Rim Brake

The BR-R451 rim brake by Shimano - compatible with 32 mm tyres

The Shimano BR-R451 rim brake is a Road side-pull brake without group integration, designed according to the dual pivot principle, i.e. it has two joints. Thanks to Super SLR technology, response and modulation are optimal. The angles of the brake shoes (not cartridges) can be adjusted. The BR-R451 brake, available in black or silver, also scores with its tyre clearance - up to 32 mm wide tyres are possible.
