Disc Brake Dual Control Lever (Wireless)

Disc Brake Dual Control Lever (Wireless)

Ultegra ST-R8170

Just like the previous generation R8070 Ultegra dual control levers, these have 'hidden' buttons on top of the shifter hoods. You can set these up any way you like and I wrote an article on just that: setting up the Di2 shifter hood buttons.

Wireless and wired

While these shift levers support the new wireless Di2 shifting, you can also choose to connect it using EW-SD300 wires. Doing so will improve battery life by approximately 50%.

These shift levers have one SD300 port and one satellite shifter (SW-RS801-T / SW-RS801-S / SW-RS801-E) port.
