This is a Specialized endurance sport hybrid bike, great for cruising and riding along the Goose with a nice light aluminum frame. It features 21 speeds with grip shifters, has a springer seat post for comfort, an adjustable stem for getting the right fit and quick release wheels and seatpost for popping in your trunk. It has 26" wheels and would be suitable for someone between 5'6 and 6 feet. I just put in two new tubes from Mec and tires from Recylistas so wheels are good and holding air perfectly. Rides, shifts and brakes fine. As with any used bike you should take to Mec or another mechanic to check out but it's in rideable shape and can be ridden home. Take advantage of the nice weather and start riding!
