Shimano 105 5800 11 Speed Front Derailleur
The Shimano 5800 front derailleur is a wide link design designed for 2x11 drivetrains. The wide link design increases rigidity and improved shifting response. The biggest difference in the new 5800 front derailleur is a longer link arm and a lower trim position. The latter helps to minimize the possibility of chain drop. New springs have also been added for faster, more reliable shifting both up and down. A new support bolt for the braze-on front derailleur provides a stable support for the derailleur and thus for reliable and precise shifting.
