Hey, had a question on these bikes. I have a Super Course from I believe 1984 (Its the Racing USA style Super Course). There is a similar model on ebay right now, (http://cgi.ebay.com/ws/eBayISAPI.dll...DME:B:AAQ:US:1) but it's a Grand Prix. What would the differences be between the two? I'm guessing components first (my Super Course has the Shimano components with the cool golden arrow on them), and the Grand Prix has Suntour.
Any help is appreciated. If nothing else, I thought the Grand Prix would make a good commuter bike.
