Shimano Ultegra Di2 R8150 12 speed rear derailleur
Shimano manufacturer reference: IRDR8150E
The Shimano Ultegra Di2 R8150 12V derailleur has the Synchronized Shift function. This allows to simplify the control of the pinions, the synchronized changes allow the cyclist to work only with the right lever "Full Synchro Shift". With this technology, a simple sprocket change on the cassette automatically determines the front chainring selection, to maintain chainline and cadence. The "Semi Synchro Shift" mode is also available and with which you will control only the command of the chainrings: the chain is automatically aligned in the best possible development on the cassette.
