Shimano Ultegra Di2 FD-6770 Front Derailleur

logo

Reliable and proven Di2 technology makes it way to Ultegra for incredibly easy and very precise shifting. The best thing about Ultegra Di2 is you get Dura-Ace Di2 performance at about half the price.

Most derailleurs use a spring and cable tension to move the chain from cog to cog. The Shimano Ultegra RD-6770 Di2 front derailleur employs highly innovative digital technology where an electronic signal is sent to a worm drive motor move the chain from chainring to chainring. Shifts are lightning-quick with no hesitation. Performance is on par with Dura-Ace Di2 except the Ultegra uses a slightly bulkier motor.

The front shifting might just be where the largest benefit of Di2 is realized for a couple reasons. Di2 front shifting is proportionately much faster than cable front shifts and this is thought to translate to a few bike lengths on the competition when cresting a hill. Also, front shifts on a cable system can be tough for riders with hand issues like arthritis or carpal tunnel. Di2 make the shifting effort just like clicking a mouse. One of the slickest features of Di2 is the auto-trim of the front derailleur. The front derailleur automatically centers itself when rear shifts are made making front derailleur cage rub a thing of the past.

The Ultegra Di2 front derailleur is one part of the Di2 system including shifters, derailleurs, battery, battery charger, and several cables/wires. The Ultegra Di2 front derailleur is not compatible with Dura-Ace Di2 shifters or first generation cables.
