Theres one NOS on ebay - for 70$

but Harris sells Suntour 5speed free wheels for 40$

Id like to keep the bike period if I can, but w/o knowing the threading I'm stuck.
Thanks in advance,

How many threads per inch is the hub? If you can count the number of threads on the hub, and accurately measure the length of the threaded area, such as with a caliper, you can compare the pitch of the actual threading with the spec threading for an English hub. If the match isn't close to perfect you have a different thread, which by elimination must be French. Someone (unfortunately not me!) should be able to tell you what the thread pitch is for a French hub.
I recall seeing a PDF of Cyclopedia on-line. Or maybe someone with an old Sutherland manual can look it up.
