Gem pumps feature a hybrid alloy/composite construction for low weight and high strength
Our lightweight Gem pumps also feature a convertible head for Presta or Schrader valves, and a patented high volume/high pressure air switch: use the high volume mode under 40 psi for quick inflation, then rotate the switch to the high pressure mode

Solid hand pump (bought this as a replacement for one I lost on the trail).
