Shimano Dura-Ace Di2 SW-7970 Satellite Shifter

After the successful introduction of the DURA-ACE group with Di2 technology in the market, it’s now time for a very interesting addition.  Shimano will offer an additional satellite shift unit SW-7970 that offers a quick and easy way to shift the rear derailleur when riding with the hands on top of the handlebars. It eliminates the need to move the hand to the Dual Control Lever for shifting, especially important when riding on cobblestones or during climbing but also very convenient for Cyclo-Cross and touring.

This additional shift unit can be mounted easily anywhere on the top of the handlebar, around the stem mount position. The Di2 cable plugs in easily at the existing DURA-ACE Di2 Dual Control Levers ST-7970.
