I have an early 90s aluminum Cannondale r900 that is a little to small for me so I am thinking about selling it. All components are Shimano 600 and everything is in good condition. Would yall advise selling it as a complete bike or trying to part it out on ebay. I believe this was a high dollar bike new, but I have never seen one of these bikes for sale and have no idea what they are worth now. Any estimates and suggestions are greatly appreciated.
