Those are really sweat and pretty rare. They run an aluminum fork with quite a rake. My brother raced a cruiser back in the 90s. Nice pickup and good luck.
Anything Cannondale bmx parts are pretty rare.Like they said the forks were aluminum an not too many sets were out there even when they were new.Post some pics so we can check your frame out.Cannondale hands down have some of the cleanest welds ever. But the decals if I remember right didnt say bmx anywhere on them.So just about any of theyre decal sets should work.
