The flagship and still most revered groupset the world over, DuraAce components stand at the pinnacle of cycling engineering- efficiency, weight, functionality, reliability; you name it and this groupset takes the cake in it. And at this level of electronic 11 speed shifting, it is absolutely what all the pros are riding on, so if you're ready to step up to full competition level, look no further than these components.
Complete Group includes every piece of the Di2 Ultegra 6870 electronic drivetrain- crankset, cassette, chain, front and rear derailleurs, brakes, shifters, bottom bracket, battery, charger and all the cables and wiring harnesses.
The default configuration settings are for an external battery and external wiring. Internal batteries and wiring are available for an upcharge.
Note: if your bars are 44cm or wider, the standard 350mm wires will be quite tight, and you may want to step up to 400mm
