Could that had been what the LBS meant? He could replace the chain but it would have to be a new chain of the right width.
Of course, we weren't there, by KimmyT's original message said this:

"the bike mechanic told him they didn't make that chain anymore. He'd have to buy a new bike."

Sounds to me like the mechanic was trying to get a quick and easy sale in addition to a classic Peugeot. KimmyT, I'd love to know what shop this was, as I used to live in DC and still go up there from time to time. But I understand if you don't want to put the shop name on the list, so if you want, PM me. I hope he gets another bike soon and a good lock. Bikes are the best way to get around DC. Driving is horrible and the Metro is expensive (and less than efficient)
