Select Ultegra R8050 Di2 Front Derailleur

Details

The Shimano Ultegra Di2 FD-R8050 Front Derailleur is redesigned to fit a wider gear pitch without sacrificing shifting performance. Quick and smooth front shifting is guaranteed under all circumstances, even when you're shifting to the large chainring while riding out of the saddle. Due to SHIMANO SYNCHRONIZED SHIFT the front derailleur will shift automatically when the rear derailleur is shifted, allowing both derailleurs to work together efficiently. With SEMI-SYNCHRONIZED SHIFT it's the other way around, with the rear derailleur shifting automatically when the front derailleur is shifted, obtaining optimal front/rear gear positioning. At the same time, Di2's auto-trim feature will automatically center the front derailleur precisely at the chain, avoiding chain rub as you move the chain across the cassette. This is how fast, precise and smooth your shifting should be.

For use with double crankset
Braze-on, clamp adaptors sold separately

Select Ultegra R8000 11-spd Cassette

Details

Superior choice is at the heart of Shimano's rider-tuned philosophy, and the Shimano Ultegra CS-R8000 11-speed Cassette reflects that philosophy with gear combinations of 11-25T, 11-28T, 11-30T, 11-32T, 12-25T, 14-28T and 11-34T (CS-HG800-11), giving you all the options you need to tune your ride. The Shimano Ultegra CS-6800 11-speed cassettes use Hyperglide sprockets with revised tooth profiles for reduced wear and lightning quick shifts. A rigid aluminum carrier keeps the cogs in check for improved shifting under the most demanding gear changes. The available ratio combinations work extremely well with standard or compact cranksets. 11-32T gear ratio requires the use of a medium cage rear derailleur.
