I know next to nothing about bmx but when I see one I think might be good in my hunts for balloon tire I pick them up. This guy seemed like it might be a good one. The frame and seat post looked different and front what I can tell online similar framed GT are good. Got home noticed it has a mongoose fork and pedals. Does this make it a part out or is that something is commonly accepted? How do you tell what year the bike is from?
