ROSE Bikes Gem mini pump| Mini Pumps

With the Gem mini pump, Crankbrothers finally solves a very old problem when inflating bike tyres: High volume or high air pressure? More volume per stroke or more reserves? The Gem answers this question, just like her big sister, the Gem floor pump (prod. code 2303169), with two separate high-volume and high-pressure modes that you can switch between with the flick of the wrist. Start with the high-volume mode and bring your tyres with just a few strokes to a good base air pressure. A simple twist at the mode dial then gives you high-pressure mode. With clearly reduced effort, you can now achieve air pressures of 9 bars and more and give your tyres the right finish. The grippy and solid aluminium housing helps you with it. With the reversible valve adapter for Presta and Schrader valves, the Crankbrothers Gem is the right choice for any bike, ranging from mountain to road bikes.
