I seem to have amassed a huge collection of bike parts. Some parts are old and need a specialist market so I don't think that ebay is the best marketplace for them. How can I sell on / give away old bike parts so I know that I'm getting the best price and/or reaching the right audience.
Depending on the urban-ness of your area, there may be local "bike swap" events once or twice a year. If you really have a lot to get rid of, this could be one way to get it in front of the right people.
