Condition

Overall, the bike is in very good vintage condition for its age and presents extremely well. It has normal scratches and cosmetic wear consistent with a vintage road bike.

There is one dent on the rear frame/stay area, which is shown in the photos. I’m disclosing it clearly so there are no surprises for the buyer. I have not represented the frame as being structurally inspected or certified.

Because of the bike’s age, I recommend having it professionally inspected and tuned before riding.

Why this one is special

Klein bikes have a strong following among vintage bicycle enthusiasts because of their distinctive aluminum frames and U.S. manufacturing history. This one also has the desirable Mavic Cosmic wheelset and Shimano 105 equipment, making it a cool combination of vintage collectible and usable road bike.

Asking $800 OBO.

Serious buyers are welcome to come inspect it. No trades.
