Lezyne CO₂ Cartridge Silver is a box of 30 replacement cartridges for riders who want to keep CO₂ inflation supplies stocked at home, in the workshop or for event support. Choose between 20 g and 25 g cartridges to suit your usual tyre volume and the amount of inflation you need after a puncture.

They are a straightforward choice for use with a compatible Lezyne CO₂ inflator. Keeping a full box on hand means you can replace spent cartridges before the next ride rather than finding out your saddle-bag supply is empty at the trailhead.

On the trail

A CO₂ cartridge is most useful when a puncture interrupts a ride and you want the tyre back up to pressure without spending several minutes pumping. Lezyne CO₂ Cartridge Silver makes that process quick, especially when paired with a controlled inflator head. The larger-capacity option is worth considering for higher-volume tyres or when you prefer a little more margin after seating a tubeless tyre.

As with any CO₂ system, keep the cartridge away from direct skin during use: it gets very cold as the gas is released.

Recommendation

Choose Lezyne CO₂ Cartridge Silver (Box of 30) if you already use a compatible CO₂ inflator and want dependable replacement cartridges in bulk. The 20 g option suits everyday carry and lower-volume tyres, while 25 g is the more sensible pick for larger-volume setups or riders who want extra inflation capacity.
