Topeak's Joe Blow Pro X.O. is sleek, durable and it fills your tires with ease. It quickly inflates tires thanks to its all-aluminum construction and its SmartHead tightly grips both Presta and Schrader valves. The X.O. uses a long braided metal hose and an oversized, tubular handle that make every pumping job easy. And, you'll also appreciate the large, easy-to-read gauge.
