The Lezyne Control Drive CO2 cartridge pump is made from CNC-machined aluminum with brass components, making it particularly durable and long-lasting. It features a neoprene cover that protects your hands from the cold generated during the cartridge discharge. The pump is compatible with both Presta and Schrader valves, allowing for easy and controlled inflation of your bicycle tire using the regulator. It is also compatible with all threaded CO2 cartridges. One cartridge is already included in the package.
