An integral part of your race kit, Innovations Cartridge Cross CO2 mounting system keeps you organized and your bike trimmed-down. Weighing in at 22 grams unloaded—a 16-gram cartridge weighs 58 grams—the Cartridge Cross bolts between your water bottle cage and your frame, and has room for four threaded CO2 cartridges (depending on the shape/curve of your down tube), thus freeing up space in your seatbag or jersey pocket. A little imaginative engineering will allow you to eliminate the seatbag altogether and run the super-sweet Cartridge Cross, pro-race-style!

*Note* Any item containing a pressurized CO₂ cartridge can only be shipped via UPS ground, and only to the contiguous 48 states.
