Galen, our Interbike video blogger, interviewed Kevin Manning at the Phil Wood booth about his Pump Hub. It works sort of like a self-inflating tire
The Pump Hub is a bicycle tire pump that fits into a wheel (specifically the wheel hub) and operates through rotation of the wheel. The pump is turned on by pushing a button, riding the bike pumps up the tire. When the tire is fully inflated, the pump shuts off.
