Matchstix from Industry Nine: $160
Industry Nine’s Matchstix turns your fork’s axle into a multitool. A sleeve that fits inside the axle holds a few bits along with a spare quick link for your chain. The handle snaps tightly into place at the end of the axle and doubles as the chainbreaker. Of course, since it’s Industry Nine, you can choose between 11 different colors for the handle to match your hubs or bike.
