Pawing through the stack of Stronglight 93 chainwheels today, I encountered a NOS 38 tooth chainring, 122 mm BCD, that looks just like a Stronglight 93, EXCEPT that the holes are 7 mm (like TA) instead of 10 mm like everything else I use. I don't know if this is for the rare Stronglight 57, which I have never knowingly seen, or for something else, but I'm happy to sell it to someone who has cranks that work with it. Seems like $16 including US postage would be about fair, but would consider trades of other chainrings.
