Thanks Jerry for the info. Indeed.. I was reading the 'Center-Center' column from Sheldons page. 122 BCD is it as you suggest.

Thanks for the tip on the bolts - I do think these ones I have will work, as the chainguard looks same thickness as the ring. If the ring I find is exact thickness as the original ones, it should work well. Wish there was something smaller than 38 workable - but this will be goin in the right direction !

I've seen a few websites which list the newer rings - but none with photos. I'm hopin the 'look' is somewhat compatible with the crank. We'll see.

Thanks for the bolt info.

Did the Stronglight's come with their own dust caps ? (forgot I'll need to find a pair of them as well !)

Thanks Rich Pinder Van Nuys, CA

>The cranks in the photo are indeed Stronglight Model 93. The BCD is 122mm. Perhaps your 71.7 is hole-to-hole? Stronglight still makes rings for these, including 38T. The new rings aren't quite as nice as the old ones, but they work fine. Harris Cyclery sells the rings, although they might have to order 38T if they don't have it in stock. They ordered several 38T for me a few months ago. It is possible the chainring bolts used by the double with chainguard will also work for a triple with no chainguard, although I've never tried that. What does work is the Sugino "old style" triple bolt set. These have no markings on the bolts (at least none visible from the outer side of the crank). The old Stronglight bolts were also unmarked, so it's very difficult to tell the Sugino bolts are not original. I've personally set up a model 93 as a triple with a 38T small ring using the Sugino bolts, and this setup works fine. The bolt sets are distributed bt Quality Bicycle Products.
