As it turned out, the increased length of un-supported axle sticking out from the right side of the hub was just too long for traditional 10 mm threaded axles. 8-speed freewheels were sold for several years, but a very large percentage of the riders who bought them wound up having problems with axle breakage/bendage.

How much wheel spacing do I need for a 7-speed freewheel?

A 7-speed freewheel needs at least 126 mm spacing, but only steel frames are likely to have narrower spacing, and they can usually be cold set to spread the dropouts. You also may need to redish the rear wheel– see article on frame spacing.

How do you remove a freewheel?

To remove a freewheel requires a special tool, commonly called a “freewheel puller ” or “freewheel extractor”, to grab hold of the core of the freewheel. This tool is a splined unit that may be mounted in a vise or turned with a wrench. The splines engage matching splines in the interior (always rotates with the wheel) part of the freewheel body.
