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.
