Technologies and Detailed Analysis

Di2 Electronic Transmission System

Shimano's revolutionary Di2 technology offers undeniable advantages over mechanical shifting systems:

• Automatic Adjustment : The system automatically adjusts itself to compensate for wear on the chain and sprockets.

Two-Way Control Capability

SW-9071 shift levers are designed to control the rear derailleur:

• Single Button Design : One lever is used for up gear shifting, the other for down gear shifting. Simple and intuitive.  .
