Here's a question I need answered.....

On the Mondia I'm rebuilding, there is a Suntour Superbe RD mated to a Suntour Winner 13-26T 6 speed freewheel. I have a spare Shimano Hyperglide 12-28T 7 speed freewheel. Can I swap them? Does the short little Suntour Superbe have enough reach for a 28T cog?

Sure would be nice to have a little more low end around all these hills......
