More Volume. More Capacity. For Bigger Tyres.
The JetBlack 25g Threaded CO2 Cartridge delivers the same instant inflation as the 16g, with the extra capacity needed for larger volume tyres. Where a 16g cartridge is ideal for road tyres, the 25g is the right choice for gravel, MTB, 29er, or plus tyres that need more CO2 to reach a rideable pressure. Threaded format, compatible with all standard threaded inflators including the JetBlack Micro CO2 Inflator.
Single-use CO2 cartridge. Best used as an emergency roadside fix — after inflation, top up with regular air as soon as possible. CO2 permeates through inner tubes and tubeless sealant faster than air. Threaded compatibility — works with JetBlack Micro CO2 Inflator (JBP-MICROJET) and most third-party threaded CO2 heads.
25g delivers full inflation for gravel, MTB, 29er, and plus tyres that need more CO2 than a 16g cartridge can provide.
Can fully inflate a road tyre and has capacity to spare — you can partially inflate if you want to control the final pressure.
Standard threaded format — compatible with JetBlack Micro CO2 Inflator (JBP-MICROJET) and most third-party threaded heads.
Suitable for both tubed and tubeless tyre setups across all disciplines.
Compact, light, and easy to carry. Slightly larger than the 16g but still fits any saddle bag alongside your repair kit.
