Shimano tools
A bicycle consists of a large number of components. To ensure that each component delivers maximum functional performance, it must be perfectly maintained. High precision, user-friendliness and a uniform design are essential for repair and maintenance tools. This is why Shimano continues to dedicate itself to the development of high-quality tools. Shimano develops professional tools to the best of its ability not only for Shimano products, but also for the maintenance of
bicycles in general. Shimano tools are designed to fit Shimano components perfectly. The tooth profile of the tools corresponds exactly to the dimensions of the components, taking possible tolerances into account.
