The new Shimano Ultegra Di2 inherited from the previous Ultegra crankset, the sprocket, brakes and chain.

New commands, the front and rear derailleur. Compared to the Dura Ace Di2, there is clearly a lower surface quality of materials, with aluminium levers and a different realization of the rear derailleur, with different materials and surface finish. As mentioned earlier, the Ultegra Di2 group has been completely revised and simplified in its construction. Also improved the ease of diagnosis. These weights declared:

Controls: 313g

Rear derailleur: 270g

Front derailleur: 162g

Battery: 71g
