Re: unique jackshafted bmx/dual suspension drive idea
cannonball i was thinking it would be easy conversion. the placement of the freewheel i was thinking have it right on the wheel not in jackshaft, eliminate as much drag as possible as soon as possible, so i would not be looking for a fw adaptor although i knew about sbp one. the dual freewheel thing was so i have in effect two drive trains with possiblity to freewheel down inclines and hills without annoying parasitic drag from a clutch. you wouldn't happen to know what largest size freewheel tooth count is available that would take a normal 9 hole back sprocket i think i seen it done that way before?
