KLEIN FRAME INFO

[Mattyboy]

Hi all

I have been given a metallic black Klein road frame which I think is a "Quantum" model from late 80s but I'm not sure.

It's aluminuum with a steel traditional looking "Klein Cro Mo" fork.

There are no lugs front or rear for mudguards.

The serial number is Q49F

Any clues or confirmations gladly received.

Thank you
Matty

Some old Klein catalogues here might be of some use to identify what you've got.

Seems it's a 1991 Quantum in "Gloss Black"

Is a frame like this safe to ride after 33 years? One sees info about 10 year max lifespan etc.

Thanks
Matty

Finished the build. Had to touch in lots of nicks and scratches before polishing. She looks pretty OK from a distance.

Yes the parts are a mixed bag but they all work well and the bike feels quick and is less jarring than I expected.
