Di2 satellite switches
Shimano Di2 SW-RS801 Satellite Shifter Switches
Wired satellite buttons that add extra shift points to 12-speed Dura-Ace, Ultegra and GRX Di2 levers, on the drops, the tops or an aero extension. Each plugs into the lever's dedicated satellite port.
Highlights
Why we rate it
Shift from anywhere
Change gear while sprinting in the drops, climbing on the tops or tucked on aero bars.
Tiny and light
The sprint and tops switches weigh about 3g each and sit almost invisibly under bar tape.
Plug-in fit
Each switch connects to the satellite port on 12-speed Dura-Ace, Ultegra and GRX RX825 levers.
Fully programmable
Assign the buttons in E-Tube Project to whatever shift function suits you.
