Folding hex wrenches live in saddlebags, jersey pockets, and frame bags because they're the tools you actually carry on a ride. Park Tool's FWS-2 puts eight hex sizes into a single folding unit that handles nearly every bolt you'll encounter on a modern bicycle. The stamped steel frame keeps the wrenches organized and provides leverage when you're torquing a stem bolt on the side of the road, while the folding design means no loose L-keys rattling around in your bag.

The wrench set covers 1.5, 2, 2.5, 3, 4, 5, 6, and 8mm hex sizes, which spans everything from derailleur limit screws to crankarm bolts. Each wrench pivots independently from the frame, so you can deploy the size you need while keeping the others tucked away. The steel construction handles the torque requirements of modern component specifications without the flex you get from aluminum multi-tools, and the hardened tips resist rounding even after years of trailside adjustments.

Park Tool machines flat surfaces onto each wrench arm, which matters more than you'd expect. Round wrench arms roll off benches and spin in your hand when you're applying torque. The flat sections keep the FWS-2 stationary when you set it down and give your fingers a stable grip surface during use. It's a small detail that separates shop-quality tools from the generic folding sets hanging in hardware stores.... Read More
