New satellite shifter for Shimano Dura-Ace Di2
Shimano are bringing out a satellite shifter for their Dura-Ace Di2 electronic groupset.
The new SW-7970 unit will let you change gear while on the tops, and simply plugs into the standard Di2 Dual Control lever.
It can be mounted anywhere on the top of the handlebar, and will be available from May 2010. Price TBC.
