I have a c. 1974 Raleigh Grand Sports 10-speed in very good condition. It has a lugged frame, which is white with turquoise trim and gold lettering & highlighting. Chrome on the lower half of the forks & rear half of the chain hangers. Most of the equipment on it is original, but I have an Ultegra rear derailleur, Planet Bike fenders, and a cyclometer. New tires. I want to sell it on eBay, but don't have any idea what it is worth. Does anyone have input? The reason I am selling it is that I cannot get up some of the hills near my home & I have three 27-speed bikes equipped with Shimano STI gear.
