The 11-speed shifters can provide multi-shifting, which can be toggled on and off. The Dual Control lever has greater grip and greater fine tuning ergonomics. Not to mention the lack of stretch or corrosion. A new feature of Dura-Ace Di2 is the option to use Shimano's synchronised shifting technology. Perfected on Shimano's XTR and XT mountain bike ranges, this system can control both front and rear derailleurs via one shift lever using a pre-programmed map.
There is also the option for the user to customize the shift map to their own preference.
