Designed and built specifically for use with any star-shaped tool fitting found on a bicycle, the Park Tool THT-1 is a set of eight professional-quality Torx -compatible wrenches made for efficiency, durability and a precise fit. Constructed from a carefully-selected combination of chrome vanadium high-tensile steel and S-2 tool steel, our T-handle wrenches are strong and durable, with several features to make them the most capable Torx -compatible wrenches you own. All three tips are precisely machined and chamfered for easy insertion into hex fittings. The sliding T-handle allows the wrench to be held in multiple positions, for improved leverage and easy access to fasteners in awkward places, and the anodized aluminum Speed Spinner makes quick work of long fasteners. The THT-1 is a complete set of the eight star driver sizes most commonly found on bicycles, so you're covered whether you're servicing a hydraulic brake, adjusting a shift lever, or removing a disc brake rotor. The set includes a durable tool holder which mounts to any wall, bench, or pegboard, for easy access and storage (mounting hardware not included).
