Heavy-Duty 38g CO2 Cylinder for Mountain Bike Inflation

The 38g CO2 cartridge is a high-pressure inflation solution designed for cyclists who need instant tire recovery during roadside emergencies. Built from precision-drawn steel and filled using strict quality control protocols, each cartridge provides fast, regulated output that restores tire pressure in seconds. Its compact size makes it ideal for long-distance riders who demand a reliable supply of compressed gas without adding unnecessary weight to their toolkit.

 

Engineered for compatibility with standard threaded bike inflators, the 38g cartridge offers higher capacity than common 16g or 25g variants—giving riders the pressure needed for larger gravel tires or high-volume MTB setups. Whether used for single inflation of wide off-road tires or multiple inflations of slimmer road tires, the 38g format offers dependable power and consistent performance throughout the entire discharge.
