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 for easier pumping up to 100 psi
All Gem pumps include a bottle cage bracket mount for convenient on-bike storage
