Yowsah! That's knee-bustin' stuff.
Back in the day, Suntour did make some 11-tooth Winner seven-speed freewheels. I've seen precisely one sell on eBay in the past ten years. I don't think they made very many at all. I presume that the one I saw was legitimate?
I have a Moulton-modified Regina CX-S that has a ten-tooth smallest cog. The moulton-sourced cogs are rather crudely-made, however.
Nothing like a 10-17 freewheel, though! 10-11-13-14-15-16-17 is the progression. Note that the 14 is the middle cog in a seven-speed!
So much for the old 'fundamental law of gearing' that stated that a 14 was the smallest gear that was possible.
