Some Suntour Mountech FD have a "step" or notch at the bottom of the cage to clear the cable and chainstay on touring bikes with lots of hanger drop.

Campagnolo 8/9 speed triple FD have short cages with inner plates that can clear half step chainring differences and smaller chainrings.

Shimano 9/10 speed trekking FD are available for the lesser angle between the seat tube-chainstay on frames with more hanger drop. The angle range is stamped on the back of the inner cage.
