The new wireless Di2 platform ensures fast and smooth shifting at the derailleur. It also offers a choice between manual shifting and synchronized shift assist modes - SEMI-SYNCHRO or FULL-SYNCHRO - that feel like your own personal assistant! In SEMI-SYNCHRO mode, the rear derailleur automatically adjusts to avoid big jumps in the gear ratio, so you can maintain your cadence and rhythm. In FULL SYNCHRO mode, the rear derailleur and front derailleur work together harmoniously so that you always have the right gear engaged and no longer need to worry. Seamless communication with the rear derailleur combined with programmed control of the chain guide minimizes the risk of the chain jumping off. The maximum number of teeth is 50-52T. It's entirely up to you how often you want to think about the gear ratio!
