Giant Cadex 26" wheels. One of the first carbon frames around. This bike is in really good condition for it's age. Really cool Suntour XC Pro components. Wheels are true. Brakes work well. Shifting works well in friction mode. Seat and grips are in good condition. Tubes and tires hold air and are in good condition. Bike is fully functioning and ready to ride, or hang on the wall as a cool piece of mountain bike history.
