Hi,

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?

Thanks!

For a 25 year old bike, I would check the tires for any cracking, replace the brake pads (they are probably hard by now), lube it and ride.

I can tell you that I have ridden bikes that were in worse condition than that one appears to be...

Unless the chain is stiff, I would drip some lubricant on the links and ride it. Surface rust on a chain doesn't look nice, but it doesn't impact functionality.

For the cassette (or possibly freewheel) surface rust isn't an issue, as long as the ratcheting mechanism etc is good.

If there is no obvious corrosion on the cables, I would apply a drop of lube in a few key locations as well.

I don't know anything about that particular model of bike, but it looks like one worth riding.

Scrub off whatever you put on the tires......... and wheels..................

Interesting, same crank as the 84 or 85 I forget which, same paint too.. I fixed one of these up for my girlfriend but hers has U-brakes, one on the chainstays no less.

Love the handlebars on that beast. ;p

I've ran across a couple of them. I actually liked the "feel" riding them. I just needed more gears.
That likely has a 6 speed free wheel & 40-50T chain rings.
IF I had it I would-
Service the wheel & crank bearings.
Lube the cables & chain.
Check tires & brake pads for function & replace as necessary.
Ride it.
