Shimano Ultegra Di2 Front Derailleur
What you need to know: Ultegra Di2 ConversionShimano's successful introduction of Di2 in its Dura-Ace group heralded a new era of shifting performance. Now those of us of more limited means can get the same smooth, electronically controlled gear changes with instant reaction, perfect precision and automatic trim, thanks to Shimano's more affordable Ultegra Di2 components. If you've seen or read reviews of Di2, you already know what an awesome technology it represents. The new Ultegra Di2 front derailleur is no exception. The "brains" of the system, it features a self-trimming function that automatically centers the cage over the chain after every shift, totally eliminating chain bounce, chain rub and dropped shifts -- sweet.
- Shimano's proven Di2 electronic shifting system now available in a more affordable Ultegra version
- Integrated CPU monitors both front and rear shifting for precise and consistent derailleur alignment
- Programmed motion allows the front derailleur to track the chain, eliminating chain drop when shifting inward from the big ring
- Automatic trim function moves the chain guide in response to the gear position of the rear derailleur - no more concentration on trimming when riding
- Rigid construction guarantees swift, silent, smooth shifting even under the most demanding of conditions
- Must be used in conjunction with the Shimano Ultegra Di2 Front Derailleur Wire Kit, Shift Levers and related system components, sold separately
- Ultegra Di2 front derailleur is not compatible with 7900 Dura-Ace Di2 levers or wire kits
