CXWXC 16g Threaded CO2 Cartridges for Bicycle Tire Inflators, Red Label Gas Cylinders in 1, 2, 4 or 6 Packs for Road and Mountain Bike Inflation Kits

Choose 1, 2, 4 or 6 cartridges

Select the quantity that suits your supply needs: one, two, four or six red-label CXWXC threaded CO2 cartridges. Each cartridge contains 16g of CO2. The option name and its quantity image identify how many cartridges are supplied. Multi-cartridge choices contain the same cartridge type; selecting a larger pack changes the number of cartridges, rather than the gas content of each individual cylinder.

Per-cartridge specifications

The 16g marking refers to the gas content in one cartridge. The source gives an approximate complete filled-cartridge weight of 57g each and approximate dimensions of 88mm long by 22mm diameter. These are reference product figures. A two-cartridge pack therefore contains two filled cylinders, while four- and six-cartridge packs contain four and six respectively. Each cylinder has the threaded neck and red printed label shown in the individual product photographs.

For a compatible bicycle CO2 inflator

A separate compatible threaded-cartridge inflator is needed to control the gas and connect the cartridge to a bicycle valve. The source does not provide a verified thread-size dimension, so compare the cartridge requirements with your inflator before selection. Presta or Schrader compatibility depends on the separate inflator head. Tire volume, starting pressure, inflator operation and the amount of gas released affect the resulting tire pressure; no universal inflation-pressure figure is assigned to a cartridge pack.

What is supplied in each option

The 1-cartridge option supplies one cartridge; the 2-cartridge option supplies two; the 4-cartridge option supplies four; and the 6-cartridge option supplies six. Inflators, insulating sleeves, pumps, tires, inner tubes and wheels are not included. Hand-held group photographs show the cartridge style from different angles and do not define a separate three-cartridge option. Use the selected option name and the matching quantity-specific image for the supplied count.

Demonstration video and accessories

The English-captioned video shows an example of using a cartridge with a separate inflator and insulating sleeve. A visible caption identifies these accessories as sold separately. The clip demonstrates attaching the cartridge, connecting the illustrated head and opening its control gradually. It is a usage example for the cartridge type and does not add accessories to any of the 1-,2-,4- or 6-cartridge options. Follow the instructions for your actual compatible inflator during setup and use.

Compare the pack before ordering

Choose the required number of cartridges and confirm the full selected option name. The quantity images show exactly two, four or six cartridges for the corresponding multi-cartridge choices. The per-cartridge specification image shows one cylinder to explain its gas content, complete weight and dimensions. All pack choices use the same source-listed red-label threaded cartridge format.
