Until early this year, this bike had been leaning against the side of my dads house. It probably spent a solid 15 years there. I grabbed it to rob the alloy hoops from it for my '60 Schwinn Jag project. Since then it has sat outside at my house. Last night I watched the Klunkerz documentary (found it cheap on Amazon), and now I want to see if I can hurt myself off road! So I grabbed what was left of the bike and started checking it out. It's a Diamondback Ridge Runner. Best I can tell is that it was built in '82 or '83, which makes it pretty old in mountain bike terms. Of course my first thought was to build it up (single speed, disc brakes), but I'm wondering now if it has any value? Should it be put back to original instead? Can anyone tell me more about this bike?
