Technology

Hyperglide
The special HYPERGLIDE sprockets are equipped with guide profiles that ensure greater control of the chain when shifting from one sprocket to another. The result is fast and precise indexed shifting.

Shimano index system (SIS)
System components such as the indexed mechanism built into the shift lever, the SIS anti-friction cable and the linear action rear derailleur are the basis of the SHIMANO INDEX SYSTEM.
