This is my pride and joy, a 1986 BMX Diamond Back. It made of airforce grade chromolly (I think thats how you spell it). It has a new chain, the original is red white blue and in my garage some where. It has a new back rim, the original rotted and was in a state of disrepair. It has a new collar at the base of the seat, new pedals because the old ones wore out, new hand grips because the old ones fell apart, and brakes, the originals were taken off and used as replacements for another bike. Any way I love this bike like crazy and hope you like it to!
