Ultegra 6870 Di2 Groupset without Power Kit

At first glance, it might seems silly to sell a Di2 groupset without what is perhaps the most important element —the battery. But, with the variety of battery and connector options out there, we felt it made sense to offer the bulk of the group this way, and allow you to choose your cable lengths and battery type separately. If you have any questions at all about how to complete your Di2 group, give us a ring and we’ll be happy to assist.

Shimano’s Ultegra Di2 groupset inches ever-closer to its top-line Dura-Ace sibling. The four-arm spider, the lever ergonomics, and even the finish on the components are top-notch. Frankly, we’re at a bit of a loss as to why you wouldn’t run Ultegra unless you were shopping for the lowest-weight option.

Included in this set are shifters, BB and crankset, derailleurs, cassette, brakes, and chain. You’ll need to acquire the battery and the connecting cables to make it all work, but it’s worth noting that Dura-Ace and Ultegra groups both use Shimano’s E-Tube connectors now, which makes shuffling things around almost as easy as it is with mechanical drivetrains.
