Cycling Tips: 10 Products I Loved in 2016 I started using Park Tool’s 3-way hex wrenches in the mid-90s and immediately appreciated the efficiency of the design. At the time, there was just one version on offer, with 4/5/6mm hex keys, and it was all that was needed to attend to most of the bolts on a road bike. It was, and remains, the perfect tool for quick assembly and checking over a bike.
