We've been receiving calls from both shop and home mechanics looking for a thin wrench to fit the centering flats, pivot nuts and lock nuts on many popular brake calipers
The new OBW-4 wrench is the answer. It has 10mm, 11mm, 12mm and 13mm openings and is specifically designed to fit the narrow flats found on some of these brakes that can make using standard wrenches difficult
This tool is particularly useful when working on dual pivot and side pull brake calipers seen on both current and older models from Campagnolo®, Shimano®, SRAM® and Tektro® amongst others
Made from heat treated, nickel plated steel for long life and with a hole for hanging on your tool board
Made in the USA and covered by Park Tool's legendary limited lifetime warranty
