Description

The PARK TOOL OBW Offset Wrenches for Brake Centring are specialist tools designed for fitting and adjusting side-pull and dual-pivot calliper brakes. Their offset design and slim profile (2.1 mm) provide access to tight spaces that are often unreachable with a conventional open-ended spanner.

The 10/11/12/13 mm model covers the most common flat sizes on modern dual-pivot callipers (Shimano, SRAM, Campagnolo, Tektro), while the 14 mm model is intended for older side-pull brakes and has hooks for handling brake tension springs.

Made from heat-treated, nickel-plated steel, they have a hanging hole for easy storage on a workshop tool board.
