Rear Mech:

Four years after the introduction of Shimano's Dura-Ace Di2 to the pro teams it was inevitable that the technology would trickle down into the top-end of the consumer market. Ultegra Di2 uses the same technologies, with four years of real-world experience to refine it, but is deliberately not compatible with the Dura-Ace version - the only component they share is the battery! So, what are you getting for the money - and it's about the same price as a mechanical Dura-Ace groupset? The advantages of Di2 (Digital Integrated Intelligence) are clear for everybody who has tested it: changing gears becomes easier, effortless and faster by simply touching the shift buttons.Instant control at the tips of your fingers. Additional benefits include an automatic trimming front derailleur, unmatched precision plus easy installation and adjustment. The nominal weight for an Ultegra Di2 rear derailleur is 270gm and it will handle cassettes up to 12-28.

£219.99

Front Mech:

The front derailleur's operation is pioneering. Smooth shifting is guaranteed thanks to a microchip communication link with the gear levers.

Fast, precise and smooth electronic shifting – even under load
Automatic trim function
Weight: 162g
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. £199.99
