9, 10 and 11 speed chains are 11/128", not 3/32". If the rings are made for 10v, you can use them with 11v chain etc., but the chainring spacing is slightly different so front indexing may be less than perfect.
Would Ultra Torque cranks in an otherwise 9 speed Shimano set-up work?

I've got 10 speed rings, but could get 9.

Thinking about shifting: do Campag rings sit further apart than Shimano?
