This is a Giant Cypress LX 21" frame bike. It has an all-Aluminum frame, Disc Brakes, 24 speed Shimano shift-gear. Front fork suspension and seat post suspension. It has always been stored in the garage and never left outside. No scratches in the frame--very good condition. I just bought and installed new tubes and Conti tires 2 years ago and put a grand total of 10 miles on it since then. Disc brakes were replaced about 50 miles ago. 700cm wheels
