Shimano original parts maintain the precision and function of the components for optimum performance, maximum safety and long durability.
Shimano's internal requirements are often higher than those of industry standards and norms. This ensures safety and reliability.
The segmentation into groups clearly divides the performance according to the top-down principle. This clearly defines the respective Shimano performance level.
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.
In combination with Shimano Hyperglide chains the HG cassette sprockets guaranteed fast, precise index shifting function. The special computer-designed sprockets feature particular tooth profiles and specifically positioned climbing aids that optimise the chain guide during shifting. This results in fast, smooth and noiseless gear changes.
