Dura-Ace 9000 is a completely new groupset for 2013. It includes Shimano's lightest, most ergonomic, and most precise road cycling components. In addition to providing the highest quality mechanical performance, Dura-Ace 9000 serves as the foundation for Shimano's revolutionary electronic shifting technology, Dura-Ace Di2. The additional 11th gear and numerous other improvements are combined to give you true dominance on the road. When you ride with Dura-Ace cycling components, you ride to win! The FD-9000-B contributes to an overall 43% reduction in shifting effort when used with ST-9000 shifters. A new support bolt ensures more stable contact with the frame and maintains the correct position of the front derailleur while pedaling. Optimal spring tension and new polymer-coated cables virtually eliminate mechanical drag, leading to increased shifting precision. 2013 model.
