Shimano to release first 105-series Di2 components 


It's bringing the function and technology inherited from recent ground breaking updates to Dura-Ace and ultegra to the 105-Di2 platform.


It comes with semi-wireless shifting and 12-speed gearing advancement 


The new 105-Di2 group set weights of 3068 grams (without a bottom bracket) and the pricing is currently slated to be near about $2000

The breaks get an update for a quieter running along with 10% more pad clearance 

It offers an expanded gear range with a new 11-36T cassette that gives a rider lower than 1:1 low gear.



The new low gear makes 105 more competitive in gear range with SRAM's Rival eTap AXS.

Shimano sticks with the same internal DN300 battery as Dura-Ace and Ultegra for the new 105-Di2 group.

In one sense charging Shimano is a bit easier than charging SRAM AXS.
