Twist-to-release valve operation separates the Lezyne Control Drive from basic CO2 inflators that dump the entire cartridge the moment you pierce the seal. The knurled control knob lets you meter gas flow precisely, which matters when you're inflating a road tire to 90 psi and don't want to overshoot and waste half a cartridge. You can release gas in controlled bursts, check pressure with your thumb, and add more as needed rather than committing to a single all-or-nothing discharge. That level of control also helps when seating tubeless tires, where you want a quick blast of volume without immediately hitting maximum pressure.

The Twin Slip Chuck head presses directly onto both Presta and Schrader valves without threading or adapter swaps. This slip-fit design creates a seal through pressure rather than threads, which speeds up the inflation process when you're standing on the side of the road wanting to get moving again. A rubber seal inside the head engages with the cartridge threads as soon as you start loading, minimizing gas loss before you're ready to inflate. That early seal engagement means you're not wasting CO2 during the loading process the way some inflators do.

Lezyne machines the Control Drive body from solid aluminum using CNC equipment, which creates tight tolerances and a durable structure that won't crack or deform over time. The machined finish also provides grip when your hands are wet or greasy from a roadside repair. At 24.2 grams for the head alone, the Control Drive adds minimal weight to your saddle bag or jersey pocket flat kit while delivering a more controlled inflation experience than disposable plastic inflators....
