Park Tool OBW-3 Offset Brake Wrench D4 The ultimate choice for racersThe Park Tool OBW 3 is a specialty wrench designed for the installation and adjustment of side pull and dual pivot rim brakes. Its unique offset design and thin profile (2. 1 mm thick with 6. 5 mm fingers) allow it to access tight places where standard wrenches would be impractical. The OBW 3 features a 14 mm open end wrench and a spring holder tool for engaging the brake tension spring that is accessible on some side pull brake calipers. Mfr Claimed
