The GMC Denali Mens Gold 700c 19'' 21 Speed Road Bike is built around a 19'' lightweight aluminum road bike frame (will fit riders 5'2''- 5'8''). You'll stop on a dime with the alloy calipers and brake levers. The high-profile alloy Vitesse racing rims look as good as they perform. Shimano Revo shifters allow you to shift without taking your hands off the handle bars providing safety and confidence. A Shimano derailleur completes the drive train for quick and smooth gear changes. Finished in a beautiful gold paint, the stunning GMC Denali Mens Gold 700c 19'' 21 Speed Road Bike provides style and the smoothest ride.
