Could you reverse the sprockets to use the other side of the teeth?
Thanks Andrew, I've already done that on maillard freewheel sprockets - just had to modify one of the splines (if that is the right word) slightly with a file.
It is interesting that with chainwheels, the manufacturer proudly proclaims that their product is made of Al 7075-T6 or whatever ( originally developed for the Zero fighter aircraft ) but the poor old rear sprockets are just steel, albeit hardened or chromed if they are posh.
