The 600 series was designed for 9 speed systems or bicycles with 27 gears

This FD-T401 (400 series) derailleur has a clamp size of 34.9 mm or 1-3/8 in , you can clamp this to the other two smaller sizes of 31.8mm and 28.6mm if you have derailleur clamp shims , they are not included with this derailleur but are available at most bicycle stores . the derailleur  is top pull , this means that the cable is pulled from the top of the bicycle .
