Park Tool Offset Brake Wrench Tool

The Park Tool OBW-4 is a specialty bicycle wrench designed for the installation and adjustment of side pull and dual pivot bicycle rim brakes. Its unique offset design and thin profile (2.1mm thick) allow it to access tight places where standard wrenches would be impractical. The OBW-4 features 10mm, 11mm, 12mm, and 13mm wrench openings to fit wrench flats found on many side pull and dual pivot brake calipers. Since our origins in the back of a bike shop in 1963, it has been Park Tool's sole mission to design and manufacture high-quality tools that empower mechanics and riders of all skill levels to service their bicycles. Each one of our 500+ tools are a product of our decades of experience and expertise in the industry, in the shop and on the trail.
