Handling should be as easy as possible and meet every aspect of a cyclist‘s expectations. This is what we call “human engineering”. The cyclist is thus assured maximum performance and maximum comfort. In order to obtain optimum performance, a complete Shimano component group (system) should always be fitted since all the individual components are perfectly matched. To make sure the system performs to the original standard, even after worn out parts have been replaced, only Shimano Original Parts should be used.
