If you're being pulled in the direction of 11 speed gearing, but don't need top tier Dura Ace or Ultegra components, look to the Shimano 105 group to satisfy your needs. The 105 FD 5800 11 Speed Front Derailleur keeps your chain aligned and your shifts smooth. The biggest difference in the new 5800 series front mechanism 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. The Shimano 105 FD 5800 11 Speed Front Derailleur is available in the color Black. It comes in braze on, 31. 8mm clamp on, and 34. 9mm clamp on.
