Well, I'm glad you've looked into the sunrace option, to (unfortunately) rule it out, but from your understanding of my suggestion you'd seem to be confused about it, and it's pretty surprising as the business is quite straightforward. At no time have I suggested mixing suntour cogs with a sunrace freehub body. I thought it was pretty clear that, when talking of mixing cogs and freehub body I was only only referring to the suntour perfect model and it's 5 and 6 speed versions. And the reason I said at the beginning of the suggestion that I only thought to suggest the quite complicated above business due to the fact that the super low gear freewheels (in 6/7 speed) were so rare, was to make it clear that my suggestion is likely the best way to go if there's no other option. So I'd advise that you read over again my last thread entry and also check other information to determine yourself if 6/7 freewheel with normal ratios exist for you to track down, then I'm sure you'd reconsider my suggestion for the suntour freewheel.
