The power house of Shimano Di2 is a long-life 7.4V Li-Ion battery that is both compact and reliable, taking shifting effort away from you.
Excellent sealing and reliability have been proven through repeated field tests in various riding conditions, including extreme temperatures, rain, mud, and cobble stone roads.
Using a hard wired battery system which is both light weight and accurate compared to current wireless technology (as a wireless system would require 4 batteries: one for the RD, one for the FD, and one for each shift lever).
The use of a single small and discreet internal battery is light weight, efficient and creates a robust and reliable system. One charge can give between 1000 and 2000 kilometre range depending on conditions and front mech operation (as this is the main power drain).
Internal chip enables system wireless functionality of Bluetooth components
Battery is to be mounted with seatpost or frame/fork manufactures hardware normally inside the seatpost or seat tube/fork steerer.
A groupset is a matched set of components from a single manufacturer that are designed to work well together. If you are upgrading your existing bike or specifying a new one, you can usually save money by buying a groupset rather than the individual parts. Pay close attention to whether all the parts will fit your frame - particularly the front derailleur. Most groupsets don't include hubs or pedals but there are many different configurations so read the component list carefully.
