i just ran into a bit of a problem which is gonna set me back big time. i got a monark double springer as a gift from my brother and the head tube which is threaded and too small for my frame. the schwinn i have takes a 1/8 headset and is way too bike to screw on to the moanrk fork... and ideas as to where i could get like a spacer or will i need a whole new fork piece? anyone willing to trade for this small one i have? any help is appreciated! thanks guys!!
