Shimano Di2 SW-R9150 Shift Switch
Shimano Di2 SW-R9150 Shift Switch Info
The Shimano Di2 SW-R9150 Shift Switch puts gear changes at your fingertips when you're riding on the tops — a small addition that makes a real difference on long climbs or extended flat sections where you're away from the hoods. These wired satellite buttons integrate with Shimano's E-tube architecture, connecting directly to the port on your existing Di2 levers without additional junction boxes.
Out of the box, one button shifts the rear derailleur up, the other shifts it down — but the system is programmable, so you can reassign either button to control the front derailleur or any other Di2 function you prefer. The kit includes two buttons (one right, one left), four zip ties, and two shroud types to mount them cleanly to your bar. Compatible with Dura-Ace Di2 9070 and later, and Ultegra Di2 6870 and later groupsets.
