CRANKBROTHERS GEM SHORT

The compact, lightweight two-stage hand pump with patented high-volume/high-pressure switching technology.

– Gem pumps feature 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 switch: use the high-volume mode below 40 psi for rapid inflation, then turn the switch to high-pressure mode for easier pumping up to 100 psi.

– All Gem pumps include a bottle holder for convenient storage on the bike.
