Shimano Ultegra Di2 ST-6770 10 Speed Shifters

These Shimano Ultegra Di2 ST-6770 10 Speed Shifters are the heart and soul of the system along with the front and rear derailleurs.

These Ultegra ST-6770 Di2 dual control levers allow you to shift and use the rim 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.
