All sorts of interesting details about SunTour. I yesterday received a Winner Pro FW from a CR member. I disassembled it to change one or two cogs. Thw Winner Pro middle cogs are different from Winner and New Winner cogs, splined instead of threaded. But the Pro body is threaded as well as notched in the middle positions, to make it backward compatible with Winner and New Winner cogs. The Winner Pro splined middle cogs are different from the inner ones, with maybe a dozen splines rather than four. Don't think the middle cogs will work in the inner position, but it is possible the inner cogs might work in the middle.
BTW I received from another CR member three 22T Winner threaded middle cogs, even though most of the literature says these didn't exist, 21T supposedly being the largest cog of this type.
