Fast air combined with light weight in a tiny package are the reasons why everyone loves using CO2 cartridges The promise has amazing hedonic value and seeing a CO2 inflator in action for the first time is equal to the wonderment of seeing a magician saw someone in half for the first time. The Lezyne Trigger Drive CO2 Kit gives you the dream. What Lezyne's design has going for it is not only the small size, or the light weight (claimed 26g), but everything. Lezyne has taken a hard look at the harsh reality of tiny inflators, and eliminated the weaknesses. The chuck is made of machined aluminum for both minimal weight and great durability. The chuck is made to join the cartridge to the valve at a right angle, so it can fit into the recess on disc wheels. The chuck itself threads onto the valve, be it Presta or Schrader, so none of the precious CO2 leaks out. And the CO2 is released via a spring-loaded trigger so you can shoot a little air in to seat the tire, then inflate the tire in slow bursts.The Lezyne Trigger Drive CO2 Kit comes with one 16g threaded CO2 cartridge. The color is Silver.Please Note: Per UPS regulations, ORM-D items such as this must ship via surface transport: UPS Ground or UPS Standard (Canada).

Screws onto tire valve

After 800 odd miles without a flat, I was applauding myself for my great ability to avoid getting flats. I immediately got a flat, which exposed the great flaw in my roadside flat preparations-the Lezyne trigger drive. The trigger drive is an L-shaped piece of alloy (beautifully made and finished). One end of the L screws onto your tire valve. Once that is accomplished, you screw the co2 cartridge into the other end. The L is spring loaded, so you can control the flow of co2 into your tire. Unfortunately, if you're like me, you will have only packed one cartridge, and you will have missed a hole in your tube that you will only notice once you start filling it. Since the trigger drive screws onto the valve before you screw the cartridge in, there is no way to remove it from your wheel without taking the cartridge off first. This means (since the cartridge is punctured) that each cartridge is a one shot affair, no second chances even if you didn't use all the co2 on the first try. The moral of this story is that if you are going to carry the trigger drive, carry at least two cartridges, or a cartridge and a mini pump.
