Accordingly, what is the advantage of di2?
The advantages of mechanical-free, electronic gear shift systems like Shimano's Di2 and Campagnolo's EPS include more precise, quicker gear changes, reduced chain wear, and the facility to allow multiple locations for shifters, making the process of swapping cogs as simple as the press of a button.
Beside above, is di2 better than mechanical? Di2 has a couple of useful advantages: Programming the buttons to operate gears (and Wahoo/Garmin computer) as you wish, as well as placing sprint/climbing shifters on the handle bars. Also with disc brakes, the hoods are significantly slimmer and better hold with the Di2 rather than the mechanical alternatives.
Keeping this in view, how good is di2?
Reliable, smooth shifting Many people swear that Di2 is the smoothest shifting available. I will confirm that it is indeed smooth and responsive when shifting both front and rear derailleur. The chain moves with precision both up and down the cassette and gear dumps (hold down the button) are rapid as well.
How long does di2 charge last?
