The next photo shows a Perfect body with three splined sprockets and two spacers in place. The red arrow points to one of the splines. The rightmost splined sprocket overhangs the larger-diameter section of the freewheel body, as shown, so that the spacer behind the next, threaded sprocket can secure the splined sprockets. | The next photo shows a Perfect body with three splined sprockets and two spacers in place.

Perfect and Pro-Compe bodies designed for the narrower Ultra (5mm) spacing have a splined section to accommodate three or four sprockets and their narrower spacers. With some Ultra-spaced freewheels, paper-thin shims are needed in addition to the regular spacers so that the rightmost splined sprocket overhangs the splines and the threaded sprockets secure the splined ones. | Perfect and Pro-Compe bodies designed for the narrower Ultra (5mm) spacing have a splined section to accommodate three or four sprockets and their narrower spacers.

With Ultra (5.0mm) spacing, the second-largest sprocket does not overhang the splines of the New Winner body, and so a special 0.9mm thick spacer allows the threaded sprockets to secure the splined ones, as shown in next photo. To engage this narrow spacer, the leftmost threaded sprocket has to have a wide flange. | With Ultra (5.0mm) spacing, the second-largest sprocket does not overhang the splines of the New Winner body, and so a special 0.9mm thick spacer allows the threaded sprockets to secure the splined ones, as shown in next photo.

When building up a SunTour freewheel, it is helpful to have an ample collection of spacers salvaged from disassembled freewheels. Sutherland's Handbook for Bicycle Mechanics, 6th Edition -- still available as a CD-ROM -- includes a complete listing of the different sprockets and spacers. | When building up a SunTour freewheel, it is helpful to have an ample collection of spacers salvaged from disassembled freewheels.
