SYNCHRONIZED SHIFT

Synchronized Shift is one of the most powerful, unique features of Di2. Map your shifts to a single shifter and control both front and rear derailleurs with one hand. Using E-Tube, you can set where your front derailleur shifts between rings. Whether you prefer a smaller ring for cadence, or a bigger ring for torque, you can position the shifter for the best progression through your gears and maintain the best possible chainline. 

SEMI-SYNCHRONIZED SHIFT

If you prefer having both shifters, Semi-Synchro Shift helps your front and rear derailleurs work together better. By programming a complimentary step of 1, 2 or 3 gears at the rear to accompany the shift at the front, you can make sure you always have the perfect gear and can maintain your stroke.

MULTI-SHIFT

With Di2 you can completely control your downshift - whether you want to shift a single gear at a time, in a burst or through the entire range in one stroke. With E-Tube you can also control how it shifts, how many gears you shift in a burst or how fast it moves through the gears.

CUSTOMIZATION

Take complete control of how your shifters work. You have the freedom to map any function to any button - whether you want to move your rear derailleur to the left-hand shifter switch the up and down gears, it is up to you. Any function can be moved to any button on the shifters.

FIRMWARE

WIRELESS CONNECTION

With Di2's wireless connectivity you can perfect your gearing trailside. If you don't yet know how you want your gears to feel, you can set up to 5 presets before you head out, then switch between them quickly until you get the feeling you want. You can also connect your Di2 to your cycling device to sync your gearing information with your other riding data.
