Crankbrothers Gem Pump
Best versatile hand pump for mountain and road cyclists.
This is the rare pump that actually bridges the gap between mountain and road riding. Its dual-piston design delivers surprising inflation power in a package small enough to vanish into a jersey pocket. You sacrifice the sheer speed of a floor pump, but you gain a reliable, do-it-all tool that saves your ride.
