What are good sites/places to buy/sell bike parts for older bikes? I've been wondering is there a marketplace to buy/sell/get original parts for bikes no longer made? I have a Bridgestone X0-1 Hybrid (the weird looking one with mustache handlebars) and I want to either restore it to original like new condition (or might just sell it) but I haven't really found a good place to research this. Any ideas?  I've tried ebay, but either its a whole bike (I don't need that) or never the parts I need!

Thanks,
Mike
In the UK you can look at Retrobike.
