Simple and effective.
The Twin Speed Drive is an amazingly compact 100% CNC-machined aluminum CO2 inflator. Using basic Twist Puncture Operation, this ultra-minimalist unit delivers easy and precisely controlled inflation, even while wearing gloves. The Twin Slip-Fit head threads directly onto both Presta and Schrader valves for secure valve engagement, and the two piece head design allows O-rings to be replaced when needed.
The Lezyne Twin Speed Drive is compatible with threaded CO2 cartridges and weighs 10 grams.
