Shimano Ultegra Di2 offers the most precise and reliable shifting imaginable, at the push of a button. Adjust the derailleurs once, and the intelligent, auto-trimming system returns derailleurs to the same position every time. The intuitive and user-friendly design can be set up at home and accommodates any frame; new or old.
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.
