Product Details

Overview & Technology

Lezyne CO2 Twin Kit combines a lightweight, threaded CO2 inflator with two 16g cartridges and a compact repair kit so you're ready for roadside emergencies. The inflator features Lezyne's Twin Speed Drive control head for precise flow, and a twin chuck head that accepts both Presta and Schrader valves without adapters. Construction blends machined aluminum in the inflator body with a neoprene and Velcro strap that keeps the kit together and protects cartridges from dings and cold. At just 180 g for the inflator and two 16 g cartridges included, the kit delivers a high power-to-weight ratio for riders who value speed and compactness.

Key Features & Real-World Benefits

The Twin Speed Drive gives you two-stage control: engage for a controlled slow-fill to avoid over-inflation, or open for a faster blast when you need quick pressure. Threaded 16 g cartridges are standard, widely available and ideal for road tires where a single 16 g can top off most clinchers. The kit's lever combo (lite gray) integrates a sturdy plastic tire lever with a small patch kit, so you can patch a tube on the spot. The neoprene sleeve and Velcro strap neatly hold everything together so the kit stashes easily in a jersey pocket or seatbag and prevents rattling on rough roads.

Fit, Compatibility & Materials

The twin chuck head is Presta and Schrader compatible, making the kit versatile across road, gravel and commuter bikes. The inflator uses threaded cartridges (2x16 g included); the control head screws onto the cartridge to create a secure, leak-free seal. There is no bracket included — the compact dimensions (7.5" x 4.1" x 1.7") and lightweight design make this a pocketable solution for on-bike carry. Materials: machined aluminum inflator body for durability and heat dissipation, injection-molded lever and patch housing, neoprene sleeve with Velcro strap for protection and retention. The design balances durability with low weight so it survives repeated use without weighing you down on long rides.

Who It's For

This kit is ideal for road and gravel riders who want a fast, compact inflation solution for race days, group rides and long training loops. If you value rapid on-the-spot inflation and minimal carrying bulk, the Lezyne CO2 Twin Kit is a practical upgrade from bulky mini-pumps. It's also useful for commuters and bikepackers who prefer redundancy alongside a compact patch kit and tire lever. Riders who regularly use tubeless setups will find the cartridges useful for quick top-ups, but should still carry sealant and a pump for reseating beads and controlled sealant application.

Frequently Asked Questions

How do I use the Twin Speed Drive safely?

Screw a 16g threaded cartridge into the inflator head until it punctures, then use the Twin Speed Drive control to meter flow — open slowly to avoid over-inflation, or open wider for rapid filling. Hold the cartridge away from bare skin after discharge; cartridges get very cold and can cause frostbite.

Will a single 16g cartridge inflate my road tire?

A single 16g cartridge will top off most 700x23–28 road tires from a flat to rideable pressure, depending on starting volume and desired PSI. For larger volume tires or tubeless setups, you may need a second cartridge or a small pump to reach final pressure.

Is this compatible with both Presta and Schrader valves?

Yes — the twin chuck head is compatible with Presta and Schrader valves without the need for adapters, making it versatile for mixed fleets and rental bikes.

Does the kit include a mount or bracket for attaching to the bike?

No — this kit does not include a bracket. It’s designed to be carried in a jersey pocket, saddlebag, or frame bag. The neoprene sleeve with Velcro keeps everything compact and secure when stowed.

Can I use the CO2 for tubeless conversions and repairs?

CO2 cartridges are great for quick top-ups and helping seat tubeless beads, but they discharge quickly and don't replace sealant. For proper tubeless conversions and long-term sealing you should still carry sealant and a pump or compressor for controlled inflation.

Are the cartridges reusable and where can I buy spares?

Cartridges are single-use; the threaded 16g format is widely available from Lezyne and third-party brands. Always use threaded cartridges that match the inflator's threading and follow the cartridge manufacturer’s storage and disposal instructions.

Buying Guide

When choosing a CO2 kit, consider cartridge size, valve compatibility and control. Threaded 16g cartridges are a good middle-ground: small and light for fast road use, while still delivering enough gas for most clincher tires. If you routinely ride larger-volume tires (gravel, fat bikes, or mountain), look for kits that include larger cartridges or carry a small pump as backup. Also weigh control options: inflators with precise bleed or two-stage control like Lezyne's Twin Speed Drive let you avoid over-inflation and reduce wasted gas. Finally, evaluate the included repair tools — a built-in tire lever and patch kit add value and let you handle common tube repairs without extra bulk.
