SHIMANO Di2 electronic shifting allows you to shift from a large chainring to a small chainring or vice versa at any time, with minimal risk of chain drop. Similarly, rear gears can be shifted without having to adjust the front derailleur to avoid chain slack. Semi-synchronous and fully synchronous shifting can be selected via the E-TUBE app. The digital precision of electronic shifting and coordinated communication between the shift levers and derailleurs ensure the SHIMANO 105 front derailleur offers the ultimate shifting experience.
