This is a 1989 Specialized Rockhopper 21 speed mountain bike. I am the original owner. I purchased it in 1989 from a bike shop in Daly City CA. It’s in generally good shape. I think the frame size is 23” ?( measured from center of front sprocket to top of seat tube ) Originally came with the Mountain LX shifters, derailers, front sprocket, and brakes system. It’s never been ridden off-road except on some paved trails. It’s spent all its life on the street. New Michelin street tires and new inner tubes. I added a rear cargo rack with slide off removable basket. Newer SCRAM handlebar shifters ( the original Mountain LX shifters broke ). BMX handlebars. Newer comfort padded seat with lighted safety light on rear of seat. Brakes are in good shape. Has paint scrapes. No rust on frame. Asking $60 cash only as is
