Shimano Dura Ace Di2 Electronic Shiftlever ST-7970
Evolution never stops. The age of electronically controllable shifting is upon us. The new Dura-Ace with Di2 technology brings shifting to a new level. Precise shifting every time and very fast in every situation - front and rear. Di2 features a similar in look to the new Dure-Ace mechanical shifter but with digital shifting for "fly by wire" stress free operation.
