Installation guide: Di2 wired shift levers
Learn how to install Di2 drop bar levers commonly used on Di2 road bikes or Di2 gravel bikes. I'll walk you through the process and give you some useful tips.
Dual Control Lever
Ultegra ST-6770
These Ultegra ST-6770 Di2 dual control levers allow you to shift and use the brakes. They weigh 160g each. Although they are part of the 6770 10-speed series, you can also use them to shift any other Di2 series derailleur. This means that if you have an older Di2 bike that you want to upgrade to a newer (rim brake) Di2 series, you can keep your shift levers.
Each shifter has two e-Tube ports each and no dedicated sprint shifter port. The SW-R610 sprint shifters will not work with these levers.
