not sure, but i would definitely keep a eye on yourself man....next thing ya know you'll be talkin about the color of your bike more than anything else, riding kids bikes with silly shifters and somehow convincing yourself schwinn actually made more than 6 different bikes in a 40 year span because the chainguard or tank changed. if you experience any of these symptoms, take a non-schwinn product for a long ride and reflect on it's awesomeness. god help you brotha.
