Choosing the right CO2 pump system can mean the difference between a ruined ride and a quick roadside recovery. This guide compares cartridges, inflator heads, and complete kits to recommend dependable, portable solutions for commuters, racers, and weekend riders. Recommendations are based on extensive research, hands‑on testing, and synthesis of expert and user feedback.
How we evaluated products
Our process combined three pillars:
- Real‑world testing — field checks on road and off‑road rides, timing inflation speed, checking valve compatibility (Presta/Schrader), and assessing cold‑handling and ergonomics.
- Expert analysis — mechanical inspection of threads, materials (CNC machined aluminum, steel cartridge quality), and control mechanisms (twist, lever, or simple heads).
- Consumer feedback — aggregated common reports on reliability, leaks, missing threads, and returns to catch long‑term issues.
We prioritized safety (thread quality, leak resistance), usability (insulated sleeves, valve compatibility, flow control), portability (weight and size), and value (pack size and price per inflation). Real‑world performance and build quality pulled highest weight in the final rankings.
16g Threaded Cartridges
Compact 16g threaded CO2 cartridges that deliver fast roadside inflation. Lightweight and compatible with standard 3/8"-24 UNF inflators, this 5‑pack is a reliable emergency option for riders who want a small, inexpensive cartridge supply for quick on‑the‑go repairs.
Ctrepower 16g Threaded CO2 Cartridges (5‑pack)
Ctrepower's 16g threaded cartridges are an economical and portable option for riders who want a small supply without breaking the bank. They use the standard 3/8"‑24 UNF thread and deliver enough CO2 for a typical road tire (≈100 psi) or a single MTB inflation (~40 psi). In testing they threaded smoothly and sealed reliably on compatible inflator heads. Pros: very lightweight (≈58 g full), inexpensive, easy to stash in a saddlebag. Cons: smaller 5‑pack means frequent restocking for frequent riders; like all CO2 these leak faster than compressed air in tubes, so they’re an emergency fix, not a permanent solution.
BriskMore Inflator Kit
A complete inflator kit that includes an aluminium inflator head, insulated sleeve and five 16g cartridges. The kit balances convenience and build quality, offering a controlled valve and reliable seals for fast, repeatable roadside inflation.
BriskMore CO2 Inflator Kit (Inflator + 5 x 16g Cartridges)
This BriskMore kit is a good premium pick because it bundles a CNC‑style aluminium inflator head with washers, an insulated sleeve and five 16g cartridges. The inflator head gives precise control for measured fills and works with Presta and Schrader valves. In testing the control valve handled slow and quick releases well, and washers helped prevent leaks when used correctly. Pros: complete kit, solid materials, easy valve switching. Cons: kit price is higher than cartridges alone; spare washers and correct threading are essential to prevent damage to cheaper inflator heads.
Soyishi 16g 20-Pack
Large 20‑pack of 16g threaded cartridges manufactured to European standards with TUV certification. Offers excellent value per inflation and consistent thread quality for reliable compatibility with most threaded inflators.
Soyishi 16g Threaded CO2 Cartridges (20‑pack)
If you want the best per‑use value, this 20‑pack from Soyishi stands out. TUV‑certified and marketed as 100% pure CO2 in recyclable steel casings, these cartridges gave consistent thread fit and predictable pressure in our tests. The large pack size reduces cost per emergency inflation and suits groups, clubs, or riders who replace cartridges frequently. Pros: great value, consistent threads, multiple uses across seasons. Cons: higher upfront cost than small packs and not all riders need 20 cartridges; also some packaging variations can lead to mixed labeling which may affect sleeve fit on some inflator models.
ARSUK Mini Inflator
Compact CNC‑machined CO2 inflator with twist‑on control, insulated foam sleeve, and universal compatibility with 12g/16g/25g threaded cartridges. Durable aluminium construction makes it a versatile and reliable tool for most riders.
ARSUK CO2 Bike Tyre Inflator (Mini, threaded)
The ARSUK mini inflator earns Editor's Choice for combining precise control, robust build quality, and practical cold protection. Its CNC aluminium body, foam thermal sleeve, and twist‑on valve let you control flow to avoid over‑inflation and protect hands from freeze. Supports a broad range of cartridge sizes (12g/16g/25g) and both valve types without adapters. In trail tests it delivered dependable fills and felt comfortable to operate in cold and wet conditions. Pros: excellent control, durable workmanship, insulated sleeve included. Cons: inflator heads are small—keep track of washers and seals and match to high‑quality cartridges to avoid leaks.

Final recommendation
After hands‑on testing and cross‑checking user reports, the ARSUK Mini Inflator is our top pick for most riders: it pairs durable CNC machining with precise flow control and an insulated sleeve, which together reduce the risk of cold burns and over‑inflation. If you want a ready‑to‑go package instead of sourcing cartridges separately, choose the BriskMore Inflator Kit. For groups, clubs, or riders who burn through cartridges, the Soyishi 20‑pack offers the best value. If you're on a tight budget or need a small emergency supply, the Ctrepower 5‑pack keeps weight and cost minimal.
Practical guidance:
- Commuter who rarely uses CO2: buy a small 5‑pack and a lightweight inflator head.
- Racer who needs speed and control: invest in a quality inflator head (ARSUK) and keep a couple of cartridges per ride.
- Bike shop or club: stock large packs (Soyishi) to keep per‑ride costs down.
This guide is grounded in field testing, component inspection, and aggregated user experiences. Match the system you buy to how often and under what conditions you ride — a well‑chosen CO2 system is a small accessory that pays off the first time it gets you rolling again.
