I'm thinking of buying a 1981 Benotto off of kijiji and, after researching, can't tell if it'll break or not. It seems like 1981 may be okay, but it's debatable. I don't know the model, but this is what the seller told me about the bike:

the brakes, cranks and front derailer say shimano 600. the rear derailer says campagnolo. as for the model, there is a sticker on the frame that says zeta and another sticker that says paris-roubaix. the front sprockets are shimano and has the symbol <52> on it.

I'd post the photos myself, but I'm at work. Any ideas on whether the bike will fail? Thanks.
