Detailed product description

The revolutionary Di2 electronic shifting system with SEIS (Shimano Electronic Intelligent System) takes the current, high-end Shimano shifting technology to a whole new level, never seen before. The increased accuracy, smoothness and reliability of electronic shifting makes changing gears even quicker and eliminates virtually all botched shifts.

This innovative shifting technology is based on the well-known Shimano Index System (SIS). The Di2 technology relies on electrical signals rather than mechanical transmission to get the shifting input across to the derailleurs.
