Fold-up hex sets live in jersey pockets, saddle bags, and toolboxes because they're the tool you'll actually have with you when something comes loose mid-ride. Park Tool's AWS-9.2 packs the 8 most commonly used hex sizes into a single folding unit that fits in your palm, giving you the ability to adjust everything from stem bolts to derailleur limit screws without carrying a full tool roll.

The size range covers real-world bicycle applications: 1.5mm for tiny set screws, 2mm for derailleur cable pinch bolts, 2.5mm for lever clamps and accessory mounts, 3mm for bottle cage bolts and cleat hardware, 4mm for the majority of stem and handlebar bolts, 5mm for crank bolts and seatpost clamps, 6mm for larger stem bolts and some pedal spindles, and 8mm for crank arm bolts on square taper systems. That's the complete range you'll encounter on most bikes without carrying redundant sizes you'll never touch.

Each wrench features a stamped steel construction with a black oxide finish that resists corrosion from sweat, rain, and whatever else your saddle bag encounters. The folding handle design keeps all 8 wrenches organized and accessible, with enough leverage to break loose stubborn bolts while still fitting into compact spaces.
