BikeTiresDirect16g Non-Threaded CO2 Cartridge (6-Pack)(Return to Product Page)

Great cartridges to save the day when �it� happens. Not jinxing it. Good price, prompt shipping and delivery.

These are great if you have an inflator which doesn't require a threaded top. Not sure which inflator BTD expects you to use this with since they don't sell one which can use these cartridges.

These cartridges (used with an inflator) get you back on the road quickly after a flat. 16 gm size fully inflates 700c, 23-25 mm tire. Adequate for my 26� mtn bike tires, too. They hold charge for years.
