ZEFAL CO2 Cartridge 25g - 2 Unit Pack for Fast Tire Inflation

Don´t let a flat tire deflate your cycling adventure. The ZEFAL CO2 Cartridge 25g 2-unit pack is the ultimate solution for rapid, reliable, and effortless tire inflation, getting you back on the road or trail in seconds. Designed for the modern cyclist who values speed and efficiency, this essential maintenance accessory ensures that a puncture is merely a brief pit stop, not a ride-ending problem. Ideal for carrying in a saddle bag, jersey pocket, or strapped to your frame, this pack provides the peace of mind you need to push your limits.

Get Back to Your Ride Instantly

The primary benefit of the ZEFAL CO2 cartridge system is its incredible speed. Forget the exhausting and time-consuming effort of a manual hand pump. With a compatible CO2 inflator, these 25g cartridges can inflate a high-volume mountain bike tire to a rideable pressure in a matter of seconds. This immediate inflation is crucial during a race, on a cold day, or when you simply want to maximize your time on the bike.

Powerful Inflation for High-Volume Tires

Specifically engineered with a generous 25-gram capacity, these cartridges are the perfect choice for cyclists running larger tires. They provide ample volume to effectively inflate Mountain Bike (27.5", 29"), Gravel, Plus-Size, and Fat Bike tires, ensuring you can achieve the optimal PSI for performance and traction. While they also work perfectly for road tires, the larger capacity offers a faster and more robust inflation compared to smaller 12g or 16g cartridges.

Reliable and Secure Performance

This ZÉFAL spare cartridge self-service package with 2 pieces, with thread, for all CO²-cartidge pumps, guarantees a secure and efficient connection. The threaded design ensures the cartridge screws tightly onto your inflator head, preventing gas leakage and ensuring that all 25 grams of CO2 are delivered directly into your tire. Made by ZÉFAL, a brand synonymous with quality and durability in the cycling world, you can trust these cartridges to perform flawlessly when you need them most. This pack of two means you have a reliable spare for a second puncture or to help a fellow rider in need.

These cartridges are a vital component for any cyclist´s toolkit, working seamlessly with a wide array of threaded CO2 inflators. Their robust construction and dependable performance make them a superior choice for maintenance and emergency repairs.

2025/07/14

sergio

The 25g CO2 cartridges are ideal for 29-inch MTB tires. If you lose your tire, cut it, and need to replace it without a suitable compressor, this is a good alternative for mounting.
