Park Tool I-Beam Mini Hex/Screwdriver Set - IB-1 $14.36
Lightweight, strong, compact tools for the road.
Double-check that you stashed the Park Tool I-Beam Mini Fold Up Hex & Screwdriver Set in your bike pack—at a slight 3.1ounces, this multi-tool's weight has a tendency to go unnoticed. The I-Beam handle makes the Mini Fold Up easy to get a grip on, while 3, 4, 5, 6, and 8mm hex wrenches provide a wide range of sizes for bolt tightening. Use the straight blade screwdriver for derailer tuning.
