Lezyne's Pressure Drive CFH mini pump/CO2 system ensures you'll always have air. First, inflate your tire with the CO2 cartridge, then top it off with the CNC'd aluminum mini pump. It includes the CO2 Flex Hose that works with both the pump and CO2 cartridges for super-easy inflation. You can also install the whole package to your frame thanks to Lezyne's all-in-one mount. You'll be back on the road or trail in no time!
