A diamond in the rough.

Inflating tires with tiny hand pumps is tedious work best reserved for trailside emergencies. Floor pumps, on the other hand, offer bigger air potential, in faster and mores table applications, and the Crank Brothers Gem Floor Pump is one to achieve just that — big pressure in short amounts of time. It uses a large chamber to send out massive volumes of air into your tire in quick pumps, and has a foot-activated switch for switching things up when you need to run high-pressure instead. When the switch is activated, the pump uses a smaller air chamber, offering shorter bursts of air, but capable of achieving pressures as high as 160-PSI, for quick-rolling road riding. The Gem comes to you ready to run both Presta and Schrader valves, and has a hidden needle and plastic valve adapter for the days when you need to pump up other sporting goods from your garage.

  • A high pressure-high volume capable pump
  • High pressure mode can achieve up to 160-PSI
  • Raised analog gauge makes for easy reading
  • Wide steel base for easy and comfortable pumping
  • Corrosion resistant alloy body comes in a range of colors

sturdy and reliable

  • Familiarity: I've used it several times

I chose this pump over a smaller more portable pump because I have had issues with them breaking in the past. This floor pump is very sturdy and fills your tires quickly. I am confidant that it will have a long life!

Great pump!

  • Familiarity: I've used it several times

This pump is great and works well with my tubeless tires! Does the job!

Nice Basic Pump

  • Familiarity: I've used it several times

Great basic pump for routine use! High volume/pressure mode worked nicely, just like the normal mode. Possibly inaccurate readying at lower pressures, but seemed more accurate as I got closer to the desired pressure, which was nice.

Great Pump

    This pump is simple, reliable, and easy to use. The perfect standard for what a pump should be. love crank bros!

    • Familiarity: I've put it through the wringer

    I bought this pump after moving to Utah and use it before every ride. Nice and light to transport with me and always reliable to measure tire pressure. I use this both my traditional road bike and tubeless mountain bike. Works great for both!
