Light is right.

Stuff the Crank Brothers Gem Pump in your pack and you'll be the envy of flat tire enthusiasts everywhere. This high-volume dual piston pump can get you all the way to 130 PSI if you need it to, and it does it in a hurry. It also does it in stylish anodized color, or in classic silver, if that's your thing. A reversible head adapts to your valve stem whether it's Shrader or Presta. The best part? The short version weighs just 128 grams, so you won't even know it's there until you need it.

The Crank Brothers Gem Pump comes in two sizes: Large (Long) and Small (Short). It's available in Green, Red, or Silver.

Continues the tradition

  • Familiarity: I've used it once or twice and have initial impressions

I have a high opinion of all the Crankbrothers products I have owned and this pump only furthers that. About ten years ago I owned one of their first mini-pumps and it lasted a long time. Just like that pump the Gem has two-stage action. It can pump either high volume, which is awesome for getting a head start on airing up a tire, or high pressure, which is perfect for topping a tire off.
This pump permanently resides in my pack and will be what I turn to should the need arise.

We have a bike that has the Gem Pump in a pack but we're not sure just how it works. It has a pressure gauge on it and kind of looks like a hammer. Do you have instructions on how to use this item>
