Shimano Ultegra 6870 Di2 Groupset

SHIMANO’s Ultegra Di2 6870 groupset provides the highest quality outside professional racing.

SHIMANO’s Ultegra Di2 series with electronic shifting is "pro-proven" as it is a direct trickle down from the Dura Ace group. It stands for state-of-the-art technology, proven in pro races, the technologies used in the new Ultegra 6870 series 11 speed included newly designed brakes and new chain treatment. The electronic shifting lets you concentrate on your performance.

The DNA for both the mechanical and electronic version of the group is the same. They share the same 4-arm cranks, 11-speed cassettes, dual pivot brakes, Sil-tec chain and 11-speed wheels. What makes them different is the shifting interface (shift lever and derailleur’s). Where Ultegra 6800 uses the well known mechanical parts and cables, Ultegra 6870 (Di2) uses an electronic shifting system.

E-tube:

  • The Ultegra 6870 products are build based on the E-tube platform and can be adjusted with the dedicated E-tube (project) software. E-tube is SHIMANO’s electronic shifting program where shifting functions can be customised. For example all the shift buttons can be individually programmed. Besides customisation, E-tube offers the possibility to upgrade components with firmware upgrades after its purchase. Due to E-tube compatibility other shifting functions are available to Ultegra 6870 like Dura-Ace sprint and Roubaix shifters. In contrast to mechanical shifting, E-tube allows a rider to install multiple shifting options on a single bike.

Ultegra FC-6800 Crankset:

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.

  • Ultegra FC-6800 Crankser, 50.34 or 53.39t

Di2 STI Dual Control Set ST-6870:

Dual Control Levers with new ergonomic design for long rides and fast accurate electronic shifting. Compared to the previous Ultegra Di2 (6770) Shimano have improved the ergonomics of the dual control lever for easier access.

Ultegra Di2 Rear Derailleur RD-6870 SS:

The derailleur’s 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. There are two versions of the rear derailleur. A SS for cassettes up to 28T and a GS for cassettes up to 32T. The 32T GS rear derailleur in combination with a compact front crank setup offer a full wide gearing setup. Both rear derailleur’s are featured with multi shifting. 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.

Rated 5 out of 5 by 2 reviewers.
Rated 5 out of 5 by Words cannot describe the sleekness and crisp shifting this groupo gives. Having decided to purchase my first serious road bike I rode countless bikes with various grupos. Veloce, 105, tiagra, rival and then this. And this swift, self correcting group set just makes cycling a joy and is virtually uncomparable, you can shift when you want without a hitch. The front derailleur is breath taking, the whirr of the motor instantaneously causes the shift. Over 500 miles into this group and hasn't once slipped or not shifted. Some cycling "enthusiasts" argue that you lose the mechanical feel of man and machine. But to those people stuck in the past if you can afford the move to di2 do it. You will not regret it. 27 June 2014
Rated 5 out of 5 by A Must Buy Now, having run the non-Di2 system for some time i decided to bag this Groupset and upgrade my Xelius. Absolutely FANTASTIC in every way! If you can afford this you will not be disappointed with the results. VERY HIGHLY COMMENDED 27 March 2014

Answer: 
These sets come as a kit. Buying individual components will always be cheaper. The crank, however, is one of the most expensive elements of the kit.
I sold on my crank to a mate who was looking for one and used my own Shimano crank.

I can confirm that these kits are fantastic value second only to including the components on a new bike. But then if you don't need a bike this is the way to go.

Enjoy.

What other components are required to fit to my Cannondale? Do I really have to braze on the front derailler? Seems a bit extreme!

Are any alterations required, or is it all a straight swap for the 105/FSA setup?

Thanks

Answer: 
Frames that do not have a 'braze on' capability you can purchase the 'band on' accessory which simply straps round the tube to do the job of the anchor points of the base on.
