OP, if you mean 130mm as the bolt circle diameter (bcd) then you should be able to get a 42t stronglight. otherwise the sugino zen messenger is 1/8" and 130bcd and is a nice ring.
i still maintain that it's more versatile to get a 18t cog than to replace a perfectly good ring, especially since it's mentioned above that it's 3/32". 49t gives you more skid patches, if that's important, and cogs are cheaper than rings.
