If you like to be prepared but are tired of your CO2 cartridges clanking against each other in your seat bag, the Cartridge Cross is your savior. It mounts beneath your bottle cage (sold separately) and securely holds up to 4 threaded CO2 cartridges. This metal carrier is built to last and it boasts an anti back-out feature that keeps your cartridges in place until you unscrew them.
Accepts all threaded CO2 cartridges (except 45-gram).
2 threaded 16-gram cartridges are included.
