This Shimano Di2 option will be an excellent addition to the aspiring racer or to the rider who just enjoys optimal performance.
This Ultegra 6870 Di2 series features "pro proven" electronic shifting, a direct trickle down from its big brother, Dura-Ace. Featuring 4-arm cranks, an 11-Speed cassette, dual pivot brakes and a Sil-tec chain, this Shimano Di2 groupset uses an electronic shifting system to let you reap the benefits of supreme shifting so you can keep your concentration where it's needed - on the road ahead.
The Ultegra 6870 products are based on the E-tube platform. They can be adjusted with the dedicated E-tube (project) software. E-tube is Shimano’s electronic shifting program that lets you customise shifting functions. Besides customisation, E-tube offers the possibility to upgrade components with firmware upgrades after the point of purchase. With E-tube compatibility you can include other shifting functions like Roubaix shifters or Dura-Ace sprint.
With a unique four-arm spider and Hollowtech II construction putting strength just where it’s needed, the FC-6800 chainset sets new standards for stiffness and low weight.

Dual Control Levers with new ergonomic design for long rides and fast accurate electronic shifting. Compared to the previous Ultegra Di2 (6770) Shimano has improved the ergonomics of the dual control lever for easier access. Especially on top of the "slimmer" hoods riders have more control than ever. Also the shape of the shift button is improved and the contrast of the surface is more recognisable.

The derailleurs are more compact and lighter than their predecessors. The rear derailleur is updated with an automatic protection system that moves the cage out of harm’s way in case of a crash. With a single press and hold of the shift button the rear derailleur goes all the way up or down the cassette. Or, when programmed at the E-tube platform, two or three gear shifts. Also the speed of gear shifts can be adjusted. In five steps, from very slow to very fast.
Fast and accurate shifting
Automatic anti-crash mechanism, coupled in an emergency the cage from the motor
Smooth shifting is guaranteed with the Ultegra Di2 Front Derailleur, thanks to a microchip communication link with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur.
Programmed Auto-Trim function
The support screw provides a rigid platform to which the derailleur can be supported on the large chainring when transporting the chain
