SEIS SHIMANO ELECTRONIC INTELLIGENT SYSTEME-Tube
Synchro-Shift
Two SHIMANO Synchronized Shift modes will be available:
- Full SHIMANO Synchronized Shift: the front derailleur reacts based on the rear derailleur’s shift action. This essentially means that, when activated, there is no need for two separate shifters to control front and rear derailleurs, the two buttons on one shifter will control both derailleurs.
- Semi SHIMANO Synchronized Shift mode: the rear derailleur reacts based on the front derailleur’s shift action, shifting to the next most appropriate rear gear when the rider makes a front shift.
