A perfectly-shifting front derailleur is a thing of beauty, but actually executing a perfect setup is challenging. Even major component manufacturers struggle to pull this off. Whether it’s the derailleur itself, or the interplay between the derailleur, chainrings, and chain, Shimano remains the gold standard for front shifting performance. The latest Shimano Dura-Ace 9100 Front Derailleur takes shift performance to a whole new level. The entire mechanism is redesigned, offering multiple cable-pull configurations and a more natural feel. What’s better is the built-in cable-tension adjuster – setup has never been easier. We’re offering the Shimano Dura-Ace 9100 Front Derailleur in Braze-On form, for use on nearly all road, cyclocross, and gravel bikes. The entire mechanism is made of a mix of high-tech alloys, for light weight and durability. The Shimano Dura-Ace R9100 Front Derailleur is an 11-speed derailleur designed exclusively for use with other Shimano Dura-Ace 9100 components.
