Review on 🔧 BikeMaster T-Handle 6mm Allen Wrench - Model 17-A06 by Joseph Swanson

When you add a stem extender to your steerer tube you have to crawl inside to get to the 6mm bolt. Tightening this bolt with a long hex wrench can be tricky since you don't have much leverage. You can use a 6mm socket on an extension and a ratchet wrench, but it's time consuming to find parts, more wrenches than you need and awkward to use (IMHO). This Bikemaster T-wrench is perfect for the job. It's the right size, one piece, lightweight and easy to handle. It also has the advantage of being able to fit in a small tool box.
