Shimanos Di2 SW-R9150 Satellite Shifters increase your shift options when youre running electronic shifting on your drop-bar bike. These are buttons to place on the tops, so you can easily shift when climbing. The basic design is that one side shifts the rear derailleur up, the other side shifts the rear derailleur down, but you can re-program the system so the buttons do exactly what you want. They could shift the front derailleur if you preferred.

These are part of the E-tube system design. That means it works with Dura-Ace 9070 and more recent and Ultegra 6870 and more recent Di2 shifting systems. There are extra ports on the integrated shifters. Youll just need to either take off the levers or peel pack the hood. In this specific case, the wires are supposed to go either under the tape or through the handlebar. So, if youve got the former, youll want to un-tape down to the levers, with the latter, youll want to guide backward from the opening at the top of the bar.

The kit comes with two buttons, one for the right, one for the left. They are wired. The kit also comes with four zip ties and two different types of shrouds to better attach these buttons to your handlebars.

The Shimano Di2 SW-R9150 Satellite Shifters make shifting easier.
