Just the same as for Dura-Ace Di2. Changing gears becomes easier, effortless and faster by simply touching the electronic shift buttons. Control at your fingertips. Additional benefits include an automatic trimming front derailleur, great accuracy plus easy adjustment and installation. Di2 continues its great success with Shimano Ultegra. And it makes no difference if these roads are cobbles, tarmac or mud.
Intuitive Shifting with Less Effort and More Precision - Anyone who has experienced Shimano's mechanical, ergonomic STI levers knows just how much control they have over all components. With Di2 technology, shifting is even easier and more 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. Shimano riders will be used to them immediately since all the buttons are in the same place as on regular levers. The distance between the lever and the handlebar is adjustable. This makes it extremely easy to brake and shift even for riders with smaller hands.
Smooth and Easy Shifting Even Under Heavy Load - The 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. This ensures that the chain never rubs. Its rigid construction guarantees swift, silent, smooth shifting even under the most demanding of conditions.
Easy Shifting at a Touch, Accurate and Effortless - The rear derailleur is pre-programmed allowing you to shift gear quickly and accurately in all conditions. The derailleur is immune to rough circumstances and protected from impact damage by its reinforced inner cage. It has a maximum sprocket of 28T for wide-range gearing.
Ultegra BR 6700 Brake Calipers - Exceptionally powerful, adjustable and controlled application. Braking is now even more powerful and faster thanks to a modified cable inlet. In conjunction with STI levers, these brakes provide the ultimate in stopping power. Improved compound brake shoes have improved braking in wet conditions by 100%. A light touch of the brakes going into a bend or a full-on emergency stop… either is possible thanks to the brakes' controlled application.
Ultegra CS 6700 Casette Sprockets - Rapid gear shifting is achievable using components that have been designed to be used with one another. The cassette is an important element in the drivetrain. This is why the sprocket design has been optimized to allow you to get the most out of the Di2 system.
Ultegra CN 6701 Chain - The forces exerted on a chain are incredibly large, yet its role is to provide smooth power transfer. The chain has a unidirectional design to reduce chain suck and improve shifting performance. This chain features perforated plates that help to reduce the weight to 267 grams.

This electronic gear change is definitely the future,spot on with every gear change and at a PBK price you'd be daft not to have it.takes a little thought to thread the cables internally but well worth the effort.

The Shimano Ultegra Di2 Groupset was well packed and delivered within 2 days but with no instructions. This was not a problem as I found them online, this is great value and one of the best cycling upgrades you can do.
