Lezyne's CNC Tubeless Drive is an innovative 3-in-1 mountain bike hand pump engineered for high-volume tubeless tire repair and inflation. The compact system combines a tubeless tire repair kit, a CO2 inflator, and a high-volume hand pump—all conveniently housed in a lightweight machined aluminum construction. The chuck is tubeless specific and “flips” for Presta, or a threaded Presta shaft (with the valve core removed) to provide more airflow when seating a tubeless tire. And the CO2 inflator allows for instant inflation and additional tubeless tire seating power. It comes equipped with five aggressive, high-quality tire plugs that are sealant friendly and one replaceable 20-gram CO2 cartridge. The rebuildable CNC Tubeless Drive is the ultimate repair setup for mountain bikes and e-bikes using high-volume tubeless tires.
