The Chorus QS front derailleurs in the 2008 range, in both the standard and compact crankset versions, have a longer front link to provide snappier and lighter shifting in combination with Ergopower QS controls. The cage is in aluminium with a surface treatment which exalts lightness and stiffness, with even more responsive shifting. The 2008 Chorus front derailleur is now designed to operate with either standard or compact gearing choices. Clamp On: 76 grams Braze On: 76g grams
