Bike Inflation Cartridges
Reach for a CO2 cartridge and a flat is fixed in seconds — no hand-pumping, no floor pump strapped to your frame. Every cartridge here is pure, clean-filled CO2 that works with standard bike inflator heads.
Pick your size
- 16g — the do-everything size for road and gravel tires (~100+ PSI in a road tire)
- 20g — a bigger burst for 29er, plus, and fat-bike tires
- 25g and up — high-volume fills for the largest tires
Threaded or non-threaded?
Check your inflator head: if the cartridge screws in you need threaded (3/8"-24); if it drops into a sleeve and is pierced when you tighten the cap, you need non-threaded. Use the Cartridge Finder if you're not sure.
