Shimano Genuine Parts maintain the precision and function of components for optimum performance, maximum safety and durability.

Quality
The quality of Shimano original parts is convincing. Every part is extensively tested and inspected. Shimano's internal requirements are often higher than those of industry standards and norms. This brings safety and reliability.

Performance
The segmentation into groups clearly divides the performance according to the top-down principle. This clearly defines the respective Shimano performance level.

Compatibility
Only Shimano original parts fit perfectly to Shimano components. The optimum accuracy of fit facilitates replacement and meets the highest demands in all respects.
