Small, medium or XXL? Here at our bike tool sets, the size differences are so similar to coffee-to-go. They can meet different requirements, so they come in very different sizes. In addition to large tool boxes that contain 30 or more parts, there are tool boxes with the 7 to 10 most commonly used bike tools that fit loosely into a bike bag. Even a set of Allen wrenches in different sizes is considered a tool set, but is of course not only to use on the bike. Our toolboxes are therefore suitable for three different areas of application, or screwdriver levels.
