Park Tool introduced the bicycle world to the three-way wrench over 40 years ago. Our Y-shaped wrenches fit perfectly in the palm of your hand and provide excellent leverage, making them a favorite of mechanics in bike shops worldwide. The ergonomically-shaped tool body features a glass fiber reinforced polymer center. Each wrench is made from heat-treated industrial tool steel for long life, with chamfered tips for a perfect fit.

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

  • Useful for disc rotor bolts (T25), chainring bolts (T30), and hydraulic brake work (T10).
