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 the Shimano components. The optimum accuracy of fit facilitates replacement and meets the highest demands in all respects.

Shimano HG (Hyperglide) chains
The chain transfers the force from the chainring to the sprocket of the rear hub. It is exposed to extreme loads and weather conditions. Chains vary in length depending on the conditions of use, but each must be replaced sooner or later. Replacing the chain in time is the only way to protect the chainrings and sprockets from excessive wear. To get the best possible performance from the Shimano HyperDrive system, it is important to use original Shimano HG chains.
