Cycling Plus
The front mech hasn't escaped the re-design process and improvements include increased stiffness to reduce snatching when shifting from small to large chain rings. While the new mech is slightly better than the outgoing version, you'll still need to toe the railing edge of the cage plate slightly outwards to get a snatch-free shift. The FD-4500 version that is intended for use with double chainsets has a short cage plate that is compatible both with normal and compact chainsets.
In conclusion...
More precise and stiffer than its predecessor, this is a good start for the set.
