I bought this 26" Diamondback Response Sport mountain bike in California in 2000 or 2001. It's a solid bike frame, and though it shows its age, the brakes & Shimano derailleurs work (3 x 7 gears). The front fork is an RST 381 EL. The seat is pretty worn, and there's some light rust in spots. The quick release levers work on the seat and wheels. Could use a tune-up & cleaning. The tires & inner tubes are original, though, so if you're going to ride it, they should be replaced (26 inch by 1.95). Message me if you have any questions.
