SHIMANO Ultegra 11 Speed 6870 Upgrade Kit


Upgrade to the pleasure of electronic shifting at a reasonable price with the Shimano Ultegra Di2 6870 Upgrade Kit, including a seatpost battery.

The Ultegra Di2 6870 groupset is a direct trickle down from Shimano’s Dura Ace Di2 9070. It offers state of the art technology that has been proven in WorldTour™ races. Nearly every component has benefitted from features developed on Shimano’s top tier groupset. The result is Dura Ace form and function at a very competitive price to appeal to cycling enthusiasts.

Shimano Ultegra shares Dura-Ace’s engineering lineage but has its own unique identity, offering greatly enhanced feel and sleek design that’s backed by a new level of performance. Ultegra blends race-proven technology with ergonomic perfection, for performance you can feel.

The state-of-the-art  technology used in the new Ultegra Di2 6870 includes redesigned front derailleur, rear derailleur and shifters along with newly designed brakes, new chain treatment, and a 4 arm crank which allows interchangeable chain rings.
