• 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
