During the 1990s Cannondale was a very innovative company and built prototypes to showcase new technology. This bike is made entirely of aluminum, including the wheel spokes and the saddle! It also has an air-adjustable rear shock, unusual for a road bike. Shifting is accomplished using an experimental compressed air- powered system developed by Shimano, hence the compressed air tank. Some of these features eventually made it into production road bikes, while others- notably, the compressed air shifter- did not.
