INTUITIVE SHIFTINGWITH LESS EFFORT AND MORE PRECISIONAnyone who has experienced Shimanos mechanical, ergonomic STI levers knows just how much control they have over all components. With Di2 technology, shifting is even easier and more precise just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear. Shimano riders will be used to them immediately since all the buttons are in the same place as on regular levers. The distance between the lever and the handlebar is adjustable. This makes it extremely easy to brake and shift even for riders with smaller hands.
