What Our Gearhead(R) Experts Are Saying:"The T-Wrench 3-4-5 lives in my seat bag and has for a long time. The one-piece cast construction means there is nothing to strip or break at an inconvenient moment, and the T-handle gives you enough leverage to actually tighten something properly rather than just snugging it up."Most roadside adjustments come down to a 3, 4, or 5mm hex. The Arundel T-Wrench 3-4-5 covers all three in a single compact tool built from one-piece investment cast chromoly steel, with a T-handle that gives you real leverage and a nickel-plated finish that shrugs off rust. Sized to live in a seat bag and stay there, this is a simple tool built to a standard that folding alternatives do not reach.
