>>1577282I'm sure its only the max cog that the derailleur can clear that is improved
I suspect they are often used in 1x setups for reason because its much simpler that way
the web sight for the wolf tooth road link shows it can be used with a 2x system, but there are specifics (such as a compact chainring(50/34t ???)
the parallelogram still has to follow the curve of the cassette cog
and the distance between the jockey wheel and tension wheel (along with how far the lower knuckle spring can rotate) is what maintains the chain tension
so the max difference between smallest and largest chain ring comes into play for chain tension
and the length and droop of the FD cage may not work well with some combinations of gear due to the angle of the chain
to give some examples from old 34 tooth SGS Derailleurs
shimano rd-ty23 and shimano rd-mr40 have very long hangers and the old style of parallelogram
the later shimano RD-TX51 GS and shimano RD-TX71 GS have shorter hangers and the newer slant parallelogram
shimano rd m340 has bigger jockey wheels and a shorter GS length cage but still manages the wrap and capacity
