Shimano 105 5800 Front Derailleur
By incorporating several features from their race-proven Ultegra and Dura-Ace groups, Shimano's 105 FD-5800 11-Speed Front Derailleur provides light, smooth and precise shifting action at a great value. Longer link arm and new spring mechanism offers clean and accurate gear changes that feel almost effortless under light and heavy loads. Lower trim position helps prevent chain drop. New support bolt for the braze-on version creates a more stable derailleur platform to improve shifting accuracy.
