Shimano 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 SM-BMR2 Junction Box A connects the electric wires from the rear derailleur, front derailleur, battery, and shift levers. The 5 Port model has extra Ports to charge, climb and time trial/triathlon shifting.
