If you're interested, I have a set of 42/52 road rings and a set of 28/38/48 
mtb rings that I'd like to be rid of. I'll trade you 5 oval rings for a set 
of 3 mtb rings. I've already bought replacements for the road bike (about a 
week after I bought it) but can't justify spending $120 ($40/ring) on the 
commuter mtb. Regretably non of my Campy rings will fit Shimano cranks.
