to get my mech cage tn clear the top ring it means the chain is catching on the bottom of the cage when its on the bottom ring.
Is there a mech with a large cage?
 
not sure about this fellow
The bikes i setup rub on the to smallest cogs or so (on the cassette), on the bottom flat bit of the cage
Not much you can do for it i dont think

Unless im terribly wrong
Maybe a shorter bb? - depends on how much adjustment you have on the mech though, may already be sat against the frame
 
mechs are specified for tooth range - think it is tooth capacity - that is the difference between the biggest and smallest rings.

sounds like the mech is not correct for your chainring choice.
