One tool for all on-trail maintenance.
Whether you have to tune your derailleur, change a flat, or fix a chain, the Park Tool I-Beam Mini Fold-Up Tool includes what you need to get the job done right. A selection of hex wrenches, a T25 star drive, and a flathead screw driver helps you adjust, tighten, or loosen just about anything on your bike. Park Tool integrated a chain tool for those nasty on-trial chain breaks, and a tire-lever helps you get peel off the rubber to replace a flat. The I-Beam Mini Tool even includes two sizes of spoke wrenches to help you straighten a bent wheel.
