The Di 2 FD-6770 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 & effortlessly smoother shifting on the front chainrings is, even under load. The difference in the effort & time to actuate the shift between mechanical & Di 2 is truly staggering. The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion & 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 & a quiet unobtrusive ride, enabling you to concentrate on the road ahead.

- 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 & the handlebar is adjustable. This makes it extremely easy to brake & shift even for riders with smaller hands. Smooth & Easy Shifting Even Under Heavy Load
- The front derailleurs operation is pioneering. Smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. Whats 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 & Effortless
- The rear derailleur is pre-programmed allowing you to shift gear quickly & accurately in all conditions. The derailleur is immune to rough circumstances & 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

Design cues & technical features taken from 7900 Dura-Ace components. The chainset has adopted the new hollow outer chainring & larger spacing between chainrings to allow a broader range of rear cassettes to be utilised. Key

Features: This Hollow Glide technology is claimed to save weight & increase rigidity for optimal power transfer & improve shifting under load. The Hollow Tech II 10-speed Ultegra chainset offers an ideal balance of light weight & stiffness, making it the perfect choice for both enthusiast & competitive riders. Hollow Glide hollow outer chainring gives vast improvements in rigidity by virtually removing outer chainring flex & hugely improves shift performance, even under high load. The chainring teeth have been developed to work in conjunction with the CN7900 & CN6700 chains for increased contact to provide greater efficiency & enhanced power transfer. Industry leading Hollow Tech II cold forged hollow crank arms have been evolved to increase rigidity, reduce weight & improve strength. A wide range of chainring options & crank arm lengths are available to meet the needs of all riders & racing disciplines. Hollow Tech II integrated bottom bracket uses a wider bearing placement & larger axle diameter for increased stiffness & efficiency. Hollow Tech II integrated bottom bracket seal design has minimal bearing interface ensuring smooth rolling & increased durability. Weight: 785g (claimed including BB). Bottom bracket is not included.
