The new and improved Ultegra R8000 front derailleur features an improved toggle link construction that matches the natural force curve of the hand when shifting, which means the derailleur moves with much less impetus, resulting in light and easy shifting. A forged wider link cradling the axle pivot at both ends, the shifting motion of this front derailleur creates one smooth, sweeping arc, nudging your chain into the right ring.Compatible with 11-speed groupsets and good for use with chainrings up to 53 teeth, the Ultegra R8000 front derailleur is available in braze on, 28.6/31.8mm and 34.9mm clamp options.Top gear teeth: 46-53TChain stay angle: 61-66Chain line: 43,5Weight: From 92g
