I'm looking for a tight-ratio 6-speed freewheel for the Mondia for use on the flats of Diego Garcia. I found this the other day on you-know-where, and it's priced fairly enough for me. But! I am wondering what's going on with the photo below:



It appears to me that there's an awful lot of exposed thread. All of my 5 and 6 speed units have no exposed thread whatsoever. Is it possible the seller simply added another cog to a 5-speed body here? If so, has anyone ever tried this? I don't need this failing on me while out in the middle of the IO

I queried the seller two days ago and so far haven't gotten an answer back.

Thanks!
