*sealed cartridge axle bearings .. Now SA has a Cassette version Too..
Ive got them on a dropout repaired MTB frame with long horizontal slot dropouts

but for now its a Triple crank & 6 or 7 speed freewheel set..
got All weather sports [Fairbanks AK ] Snow Cat (45mmwide) Rims, and Nokian Mount and Ground W tires on it ..
