Instant Response

Electronic signals between the shifter and the derailleur(s) give mountain bikers an instant connection to a wide range of gears… making it easier to react and stay in the flow of the trail. React instantly to sudden changes on the trail quickly and efficiently allowing you to save energy or find even more speed. With Di2 you can pre-program the system to shift through your whole cassette by simply holding down the shifter. Or if you prefer a traditional approach, tap away every single shift. The decision is yours.
