Cycling can be pursued as a recreational activity or a professional sport. Cyclists need basic, portable equipment such as hand pumps, because at some point, all bicycle tires must be re-inflated or repaired. Hand pumps provide cyclists with the ability to inflate bike tires on the trail or at home.
Performance
The best hand pumps offer the highest stroke force and maximum pounds per square inch, commonly referred to as PSI. Stroke force refers to your ability to operate the pump and the number of strokes needed to inflate a tire. Maximum PSI output refers to the maximum amount of air pressure the pump can exert. The best hand pumps can reach 160 PSI.
Features
Additional features set the best hand pumps apart from basic models. For example, the best hand pumps feature a folding foot support and flexible hose that allow you to inflate the tire from any position. A padded T-handle protects your hand while pumping, and a clamp mount allows you to mount the hand pump to the bike frame. Built-in pressure gauges allow you to test the PSI to avoid over inflating the tires.
Valves
Bike tires have three types of tire valves: Schrader, Dunlop or Presta. Most hand pumps are designed to fit only one type of valve, but the best hand pumps feature all valves adjustable connecting systems, commonly known as AVACS. This feature allows the hand pump to fit on any valve without resetting or adjusting the pump.
Considerations
Hand pumps are essential for cycling and can be purchased at outdoor recreation stores, bicycle specialty shops and online bicycle retailers. As of 2011, the best hand pumps range from $20 to $40, depending on added features and accessories.
