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.
The Shimano Ultegra SM-BR1 battery mount holds the battery securely to frame. The mount is available in three styles: a long mount for external routing, a long mount for internal routing, and a short mount that is designed to be used on bike frames that bear a specific Di2 battery mounting location. Battery sold separately.
