I bought it, and the ad said it was a Dyno, but I am fairly sure it is a Diamondback Joker. The serial number is DB S1C00050. Around what year would it be from? I was curious if it was a good deal, since I saw that theyre selling for about 200 at dicks sporting goods. got it for a lot less than half that price. condition is fair, slight surface rust, but i plan to clean and paint anyways. Thanks in advance!
