Topeak’s Transformer X is a portable floor pump and bike stand combination. The adjustable stand has two hooks that hold your bike upright for repairs or tire inflation via the chainstays and seatstays. Its gauge is attached to the pump’s handle for simple reading, and Topeak’s SmartHead works with any type of valve you’ve got. An extra-long hose and included ball/bladder needles make it easy to pump up just about anything.
