Part of a range of wrenches with offset heads to improve access in awkward places
Specially shaped and sized for specific bicycle jobs, especially on brakes
14 mm open ended wrench on one end, with lugs on the other end that locate into the tension springs on calliper brakes
We call these our offset wrenches because of their unique design, which allows them to be used in tight places, such as centering caliper brakes. OBW-3 has a 14mm opening, and the other end fits into the tension springs to rotate the brake on its bolt.
