There are almost always a few NOS Suntour freewheels with 5-speed 14-38 gearing for sale on ebay. Because I had a Huret Duopar derailleur, which was rumored to be able to handle the 38-tooth cog, I bought one a few years ago and set it up on my Gitane tour de France with a half-step 48-42 double in front. It shifts well, has fairly even jumps between gears, and is kind of fun to ride--half-step gearing does give you something to do besides just pedal.
What happens to those other freewheels, though? I assume that some of them must be sold to people on this forum. Who's using them, how, why, and with what derailleurs? Just curious--and wondering what to do with my other Duopar
By the way, ignore the horrible bar tape in the photo--it's gone now, along with the computer and bottle cage.
