Torx fasteners keep showing up in more places on modern bikes. Disc brake rotors, chainring bolts, brake lever clamp screws, stem faceplates — if you're doing your own service work, you need a dedicated Torx set, not just whatever L-key came in a blister pack. Park Tool's THT-1 Sliding T-Handle Torx Wrench Set covers all 8 star driver sizes common to bicycle applications: T6, T8, T10, T15, T20, T25, T30, and T40.

Each wrench is built from a combination of chrome vanadium high-tensile steel and S-2 tool steel, which gives you both hardness at the tips and toughness through the shaft. Every wrench has 3 Torx-compatible tips: the primary working end, a second tip on the opposite end of the T-handle, and a third at the end of the long shaft. That third tip is the one you'll use with the anodized aluminum Speed Spinner sleeve on the shaft body — hold the spinner between your fingers and let the shaft rotate inside it, so you can run long fasteners in and out without re-gripping the T-handle on every turn. If you've ever threaded a long disc brake mount bolt in by spinning the whole tool, you know why that matters.

The T-handle itself slides along the shaft with enough friction to hold position, so you can shift the leverage point depending on the job. Slide the shaft off-center for more torque, or center it for balanced two-finger spinning. One end of the T-handle also carries an integrated Strip-Gripper — a twisted Torx profile designed to bite into stripped or oversized star fittings and back them out. It's the kind of feature you don't think about until you're staring at a rounded-out rotor bolt, and then you're glad it's built into the tool you already have in your hand.... Read More
