I've been riding my Cannondale around Cocoa Beach, Orlando, and Merritt Island for 16 years- I bought it with my first full pay check when I finally got a "real job" after college. I've taken it to Europe, where I rode from France into Switzerland and back (not really that long a ride, but it was hillier than I'm used to here in Flat FLA.) Most of my riding is urban, on surface roads and bike paths, but I have no problem taking the bike on the beach at low tide. A very good rinse in fresh water, a few hours drying in the FLA sun, and more oil, and it's fine.
I've replaced parts that wear out after literally thousands of miles, but no big overhaul.
I hadn't ridden in about three years, but I had taken up jogging. Then I fractured my tibia and can't jog anymore, so I'm back on the bike. Why did I ever quit???
I ride almost daily, but as I get older the heat really gets to me sooner, so I don't seem to go as far as I used to. I was 25 when I bought the bike... I'm a little slower now, but no less nimble.
I've got some tech. questions, which is why I joined the forum. I'll post them wherever they belong.
If you're in Brevard and see a guy on a black Cannondale with a white helmet sweatin' like crazy, wave at him!
