I have not yet sold a bike or frame on ebay, but we have sold many bike parts on there. Some things sell for more than I expect, some for less. We have some frames here that need to be sold. My SO has a fancy steel Colnago frame he wants to sell eventually. He's been watching auctions for similiar items to see what he might get for his.

I did buy a nice frame on ebay in the spring. It's a 13.5" Gunnar Rockhound mtn bike. It's a sweet steel frame that retails for around $800. I got it $200
