These days, the Wera Zyklop Pocket ratchet is my go-to tool for any kind of bicycle-related maintenance. It is easily small enough to fit in my hip pack and I carry it everywhere I ride. Get a few additonal bits to fit the particular requirements of your bike and you’ve got a fantastic tool that, because of its ergonomic properties, represents a significant step up on any of the traditional multi-tools.
