Crank Brothers

Co2 Cartridge - Threaded

What Our Gearhead® Experts Are Saying:

"I keep a 16g for road days, but when I'm running plus tires or enduro setups, the 25g cartridge is the one I trust. The Crankbrothers inflator is compact, efficient, and threads easily—it’s the first thing I check before heading out."

Flats are never fun, but getting rolling again doesn’t have to be a pain. The Crankbrothers CO2 Inflator is our quick fix for mid-ride pressure drops, available with your choice of 16g, 20g, or 25g threaded cartridges. Whether we’re kitting up for a gravel grind, long road loop, or chunky trail ride, we pick the cartridge size that matches our tire volume and ride demands.

The Klic inflator head is sleek, intuitive, and built to perform. Thread it onto a Presta valve, release, and watch your tire snap back to life. No fiddling, no extra bulk, just reliable inflation in seconds. Each cartridge size is sold separately, giving us the freedom to carry just what we need for each adventure. And when every ounce and second matters, that’s a win.
