i just pulled a flash looking "QUAKE PROOF BIKE" out of a skip (dumpster) its got full suspension and realy heavy duty motorcycle style forks (true tripple tree) its just screaming to be fitted with a large hub motor. i stripped it back and gave it a nice coat of matt black, fixed some bits and peices then came up against something new-threadless forks! ive got the lower forks, a pressed steel top yoke and the stem, ive been looking around and found a handle bar mounting stem to fit but how do i keep the bearings tight? i think i needa sealed top bearing? will this maintain preasure on the bottom bearing (which seams to be a conventional type)? realy excitedabout this find i know its not the moste prestigious suspension bike but its got some lovely touches? anyone know anything about them?
