Most hex and Torx fasteners on a modern bike fall within a narrow range of sizes, but keeping a full set of L-wrenches organized in a toolbox or saddle bag is a losing battle. Park Tool's FWS-2 Fold-Up Wrench Set solves that by bundling 2 fold-up tools — the AWS-10 hex set and the TWS-2 Torx-compatible set — so you get 16 wrench sizes across both tools without loose pieces rattling around.

The AWS-10 carries 7 hex wrenches: 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, and 6mm. That covers seatpost clamps, stem bolts, brake calipers, derailleur limit screws, and most cockpit hardware. The TWS-2 carries 9 Torx-compatible wrenches: T7, T9, T10, T15, T20, T25, T27, T30, and T40. Torx fasteners keep showing up on disc brake rotors, lever clamps, derailleurs, and stems, so having the full spread from T7 to T40 means you're not caught short when a bolt head turns out to be star-shaped instead of hex.

The wrenches themselves are industrial tool steel, through hardened and tempered, with chamfered tips that seat cleanly in fastener heads without the slop you get from worn or undersized tools. The handles are a composite material — not steel — that Park Tool rates at 40% stronger than steel handles while staying lighter and corrosion-proof. Each wrench locks into multiple positions within the handle, which gives you options for reach and leverage depending on the fastener location. Both tools are compact enough to toss in a saddle bag or hydration pack for trail-side work, but they also hold up to daily use on a shop bench.... Read More
