I guess I should have been more specific. My needs are for a 3/32 ring since I single speed and don't run a 1/8" chain. It appears that Stronglight has a 46T ring which may help a bit.... I may just have to bite the bullet and move to a 17/19 dos eno and a larger front ring. It sucks that I have to replace my whole drive-train to get a different gear ratio. Times that by two since I have two wheels sets for my SS. So new chain $50 (KMC hollow pin), $200 for 2 Dos Enos, and ~40 for a new front ring. I guess I just need to learn to like my current setup.

Thanks to all for the pointers on possible c-ring sources for 135 bcd
