I have a recently acquired Diamondback Fleet Streak bike that my grandpa has had in his garage/the side of his house for the last ...25 ish years (based on the little information I could find on when this bike was produced). Since he's had it covered in a very dry climate, it seems to be in pretty good condition.
I'll be taking it to my local bike shop hopefully this week. I'm pretty sure they'll be telling me I need a new cassette and chain. Every other component looks to be wear and rust free.
But can anyone tell me anything about this bike?
