Over 40 years ago, Park Tool introduced the bicycle world to the three-way wrench. These Y-shaped wrenches fit perfectly in the palm of your hand, providing excellent leverage and making them a favorite among bike shop mechanics worldwide. The ergonomically shaped tool body features a glass fiber reinforced polymer center. Each wrench is crafted from heat-treated industrial tool steel for durability, with chamfered tips for a precise fit.

The TWS-3 includes three of the most popular star driver fittings found on modern bicycles, allowing for easy adjustment of disc rotor bolts, chainring bolts, and hydraulic brakes.
