Shimano Ultegra 6770 10 Speed Di2 Upgrade Kit
Building off the tried and true reliability and functionality of the 10 speed drivetrain, Shimano built the 6770 Di2 Groupset around maximum compatibility. With the ability to fit a 10 speed cassette on just about every freehub out there, this is the drivetrain of choice for those with a dedicated set of 10 or 9 speed wheels. The Ultegra series is Shimano’s performance proven electronic group as it is a direct trickle down from Shimano’s Dura Ace group.
Upgrade kit includes everything needed to move from a current 11 speed mechanical drivetrain to an electronic one- front and rear derailleurs, shifters, battery, charger and all the cables and wire harnesses.
The default configuration settings are for an internal battery and internal wiring.
