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.
KEY FEATURES:
- Frame Junction Box connects via SD50 E-tube wires to four different points: front derailleur, rear derailleur, cockpit junction box and battery mount
- All Di2 components on the bicycle require the same firmware version. Using Di2 components with different firmware versions may cause malfunctions
- Use Di2 system checker to update component firmware from http://e-tubeproject.shimano.com/
