Three-way wrenches put multiple sizes in your palm without digging through a drawer, and the Park Tool TWS-3 handles the Torx fasteners that show up on disc brake rotors, caliper mounts, and certain stem interfaces. The Y-shaped body gives you T10, T25, and T30 on a single tool—three sizes that cover the most common Torx bolts on modern bikes. Spin it between your fingers for quick threading, then grip the other two arms for final torque.

The size selection here isn't random. T25 handles six-bolt rotor mounting, which is where you'll use this wrench most often. T30 shows up on some crank arm pinch bolts and occasional stem hardware. T10 covers smaller fasteners like certain brake lever clamp bolts and some electronic shifting components. Between those three sizes, you've got the Torx range that actually matters for routine maintenance and trailside repairs.

Each arm uses a bonded construction that permanently fixes the bit into the handle body. Unlike socket-style tools where bits can work loose or get lost, there's nothing to separate here. The stamped size markings on each arm let you grab the right one without trial and error, even when you're working in low light or at awkward angles under a bike.... Read More
