Product Details

Overview & Technology

Lezyne threaded CO2 cartridges deliver instant inflation with compact, high-strength canisters engineered for reliability and ease of use. Available in 16g, 20g and 25g sizes and sold in 5- and 30-unit packs, these cartridges are precision-formed from high-grade steel with a threaded neck to screw directly into compatible inflators. The threaded design makes them compatible with most popular CO2 inflators (including Lezyne's threaded drivers), creating a secure seal that reduces gas loss during use. Real-world benefit: quick top-ups at traffic stops, before group turns, or on long rides when a track pump isn't practical.

Key Features

Size-specific performance: a single 16g cartridge inflates a road tyre up to ~120psi and a typical MTB tyre to about 30psi; a 25g cartridge will fill a 26" x 2.5" tyre to ~40psi or larger 29" tyres to useful pressures. The 20g option provides a mid‑range capacity for mixed-use riders. Construction & packaging: high-strength steel canisters with a threaded neck for secure inflator coupling, sold in bulk 5‑packs or value 30‑packs. Lightweight and compact, they stow easily in saddle bags, jersey pockets or multi-tool kits.

Fit & Compatibility

These cartridges are threaded—they screw into compatible threaded CO2 inflators rather than attaching directly to a valve. They work with most modern threaded inflator heads, including Lezyne's Control Drive and many aftermarket models. The inflator head, not the cartridge, determines whether you can inflate Presta or Schrader valves. Note: threaded cartridges are not interchangeable with non-threaded (pierce-style) inflators. Always confirm your inflator head uses threaded cartridges and follow the inflator manufacturer's instructions for safe use.

Who It's For

Ideal for road cyclists who value fast, lightweight emergency inflation on club rides and races — a single 16g cartridge will get a road tyre to serviceable pressure in seconds. Gravel and weekend riders who want compact backup inflation for mixed-surface outings will also benefit from the 20g or 25g options. Carry two cartridges for long rides or group events: one to get you rolling and a spare in case of a second puncture. Mechanics and bike shops appreciate the bulk 30‑packs for service kits and floor-stock.

Frequently Asked Questions

Are these CO2 cartridges reusable?

No. Lezyne CO2 cartridges are single-use canisters. Once pierced or fully discharged they cannot be refilled and should be recycled or disposed of according to local regulations.

Which cartridge size should I carry?

For road rides a 16g cartridge is usually enough to top a tyre to pressure quickly. If you run larger gravel or MTB tyres, choose 20g or 25g for greater volume. Many riders carry two 16g cartridges or one 25g plus a spare depending on ride length.

Will these work with my Presta valves?

Yes — when used with a compatible threaded CO2 inflator head. The cartridge screws into the inflator; the inflator head then clamps or threads onto Presta or Schrader valves depending on its design. Check your inflator's compatibility before use.

Do CO2 cartridges get cold when used?

Yes. Rapid gas expansion cools the cartridge quickly and it can become ice-cold. Use a protective sleeve or hold the inflator, not the bare canister, to avoid frostbite or cold-hand discomfort.

How should I store and dispose of unused cartridges?

Store unused cartridges in a cool, dry place away from heat and direct sunlight. Empty cartridges should be recycled where facilities accept steel aerosol-type canisters; if unsure, follow local waste management guidance for pressurized metal containers.

Can I mix these with non-threaded inflators?

No. Threaded cartridges are specifically designed for threaded inflator heads. Non-threaded (pierce) inflators require non-threaded cartridges. Using the wrong type risks gas loss or damage to the inflator.

Buying Guide

Choose the cartridge size based on tyre volume and the pressure you need. 16g cartridges are compact and ideal for road tyres where high pressure is required; 20g and 25g give more volume for larger gravel and MTB tyres. Buy the pack size that suits your use — 5‑packs for casual riders, 30‑packs for workshops or frequent riders. Confirm your inflator head is threaded before purchasing threaded cartridges. Consider a small protective sleeve and a lightweight inflator head with pressure control if you want more precise inflation and longer valve-to-tire fills.
