A bicycle consists of a variety of components. In order for each component to deliver maximum performance, it is essential that it is perfectly maintained. High precision, user-friendliness, and a uniform design are crucial for repair and maintenance tools. This is why Shimano continues to focus on developing high-quality tools. Shimano develops professional tools not only for Shimano products but also for the general maintenance of bicycles. Shimano tools are designed to fit Shimano components perfectly. The tooth profile of the tools matches the dimensions of the components precisely, taking possible tolerances into account.
