As a new Stronglight 93 crankset owner, I have been looking around for the purposes of laying in provisions for the long, cold, parts-shortage winter arrives. I have found the following sources for NEW/NOS 122 bcd chainrings :

NOS stronglight rings (38-52T) :

Custom chainrings :


However, Sheldon Brown doesn't know if his stronglight rings are 93-pattern, and malc cowle at withington cycles says his definitely are not - they look more like super record chainrings. I presume that Sheldon and Malc are getting rings from the same source.

So I have two questions :

(a) Have I missed any (non-ebay, non-CR-list) sources for 122 bcd rings ?? In particular, who else (Jim Merz?) will do a run of custom chainrings, and how many are necessary to make it worthwhile?

(b) At some small tooth count, e.g. 38-44, maybe, I figure that even campy lookalike rings and stronglight 93 rings will be nearly identical because the aluminum must support the teeth and run between the bolt holes. At what tooth count do the new rings match or almost match the old ones ??
