The Shimano Ultegra series is "pro-proven" as it is a direct trickle down from our Dura Ace group. It stands for state-of-the-art technology, proven in pro races, the technology used in the new Ultegra 6800 series with 11 speed, newly designed brakes, new chain treatment etc.
Ultegra now has an 11-speed cassette with numerous gearing options to cover all situations. Leading edge design, materials and construction reduce weight, improve stiffness and enhance control.
Crankset ( Bottom bracket is BSA threaded english standard )
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 STI Shifters
With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear. The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts.
Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold. The drop bar STI with shift buttons located in a near identical place to the positions you'd assume shifting using a mechanical Shimano STI. Brake lever pivot is positioned to be used with super SLR brake callipers, increased power providing excellent ergonomics when riding on the hoods.
Ultegra Rear Derailleur
With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear.
Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift. The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts.
Ultegra Front Derailleur ( BSA threaded english standard )
The Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur. The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load.
The difference in the effort and time to actuate the shift between mechanical and Di2 is truly staggering. The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts.
The front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road ahead.

Super sweet. The look is awesome and the shifting is perfect. The only down side is the provided bottom bracket was useless and an option is needed during ordering, the same with the provided grommets. The internal battery also needed an option for a mounting bracket. Even with those three things I am extremely happy with the purchase. Add in the sale price these Di2's can't be beat.
