Yeah I'm pretty sure I do. I know I have several 38t, know I don't have 39t (never seen one), and probably do have at least a couple 40t.
They're in the basement though, and I had abdominal surgery yesterday, still am not ready to walk down a flight of stairs.

Price for a NOS 38t is $60, sorry so expensive but that's the most popular size for most anyone old enough to be into SL93. Old dudes tend to want lower gears. Early-'70s PX-10 for example often (usually?) came with a 45t inner and that's not low enough for me and my ilk. My supply of 38s is intended for my bikes, I'm not a dealer just a hoarder.

Oh and if that's not low enough, I can sell a 36t for $100. That's not a size SL made in 122 mm BCD, so I made a couple using 36t SL 99 rings. I drilled new holes at 122, counterbored them, and cut the old 86 mm BCD holes off. The outer tips of the 5 spider arms on the crank have to be trimmed to use a 36t, else the chain hits there. Pics on request. Clearly, this is going to have limited appeal for anyone but a confirmed Stronglight geek. I am one of those of course, but there probably aren't many others, not gonna sell a lot of those at that price! Just thought 'd mention it.

Not sure if I have any used 38t but if I do they'll be less, down to maybe $15 for well-used, maybe $40 for lightly used.

If I have used 40t rings, those prices will be lower than for 38t due to being less in-demand. I don't have an inventory in my head and can't go look right now, so hopefully you're not in a hurry.

BTW check out Spa Cycles in the UK. I haven't looked lately but as of a few years ago they were selling SL 122 mm BCD rings that were recently made, like in modern hard alloy (7075) and anodized, technically excellent though they don't look right on a vintage crank. If you just want a rider not a concours-caliber restoration, then that's the smart way to go. Though what with tariff and whatever handling fee the parcel company tacks on for taking your money, it might be expensive — sorry I don't know. And if Spa could get them from SL, then other retailers probably could to, I just haven't seen any.

If someone here knows of a source in the US, do let us know.

Oh here's a couple pics of the 36-45 crank I made for myself recently, and the drilling jig I made to do them on the mill. I can make other sizes too, the limiting factor being availability of the "raw material", which is SL 99 rings in the size and condition you want. If you have a 99 ring you want converted to 122 mm BCD, I'm your guy.





That's not the finished pic of the jig, that's a work in progress. As I drilled the 5 new holes at the 122 BCD, I drilled right through the jig as well as the ring. So the jig can now be used in any old drill-press, doesn't need a milling machine. Just filp it over, and the holes in the steel jig act as drill bushings to align the drill, to drill through the ring bolted to what's now the bottom of the jig. I did a second one that way on the drill press as a proof of concept, went super fast compared to using the digital readout on the mill to position the holes. Pics of the finished jig on request, once I can walk down the stairs...

Oh and I also used that jig to make Triplizer rings, to replace the inner on a 93. It becomes the middle ring of the triple, which also has holes at 86 mm to take a granny down to 28t. This is one I made for me, 28-38-45, not for sale, but I can make more triplizer rings if there are lunatics like me who like the idea.





To be clear, you need a 99 ring to make it out of, and if you have a 99 crankset, you should just use it. Or use any other good triple crank, if triple is what you want. There's no advantage to tiplizing a 93 that I can think of, other than to say you did. It's a little crazy. (I like 'em though!)
