What is Shimano Di2 groupset

Do I really need Di2
It's a more consistent shift. You will hit the gear you want every time, perfectly. It does give you a competitive edge and most people who've ridden both will prefer Di2 because it's just a little more precise, and a little more accurate.”
How do Di2 gears work
Di2 does more than just cutting friction. … Di2 is programmable to allow you to shift through multiple gears at once by holding down the shifting button. Perfect for wide gearing swings like the transitions from gulley to switchback on a trail ride or from off the back to chasing back on in a road race.
Which is better Dura-Ace or Ultegra
Although Dura Ace is considered to Shimano's out-and-out performance groupset, surprisingly, Ultegra is generally deemed to be much more versatile, mainly because of the lower range of gears that it offers. While Ultegra cassettes go all the way up to 34 teeth, Dura Ace cassettes only go up to 30 teeth.
Is it worth upgrading from Ultegra to Dura-Ace
The quality of the Ultegra and Dura-Ace components is almost identical, but Dura-Ace is slightly lighter. If you're a competitive climber to whom a few grams of weight savings makes a big difference, then Dura-Ace would be justified.
