The Topeak Transformer Floor Pump lets you forget the hassle of propping your bike on some foreign object while you inflate your tires and adjust air pressure. Adjustable seat and chainstay hooks slide up and down to accommodate a wide variety of bike sizes and frame types, while the built in legs support your bike much like a kickstand. Both the hooks and legs fold out of the way when you're not using them, helping to reduce overall bulk. The pump itself is made of lightweight alloy for durability and ease of transport. Its SmartHead features an air release button for compatibility with both Presta and Schrader valves. Maximum pressure is 160PSI, with an easy reading gauge for precise inflation. Moreover, it includes a ballbladder needle and Dunlop valve adapter.
