All the tools you need in a handy compact format – that means Allen keys of different sizes, Phillips and Torx screwdrivers, and, depending on the model, a chain tool, tyre levers, a spoke wrench and more. Most mini tools are designed according to the pocketknife principle and combine a variety of functions. When it comes to multi-tools, it's not about being able to solve all conceivable problems, but rather about the best compromise between useful tools, a compact design and low weight – although you can fix a lot on a modern bike with only a few tools. A mini tool with a chain tool, two tyre levers, a repair kit and a mini pump will cover most eventualities.
