Don't get stranded in the middle of nowhere with a flat. Instead, pick up the Lezyne Repair Kit for everything you need to fix your punctured tube. This repair kit contains a reusable storage bag and Lezyne's Twin Speed Drive for easy inflation with both Presta and Schrader valves. Its two piece head allows O rings to be replaced when needed for easy maintenance. This CO2 inflator is only compatible with threaded CO2 cartridges and comes with an anti freeze jacket to protect your hands during inflation. Inside this handy little kit, you'll find two 16 gram CO2 cartridges for quick and easy tire inflation. It includes Lezyne's Smart Kit, which includes six glueless patches with aggressive adhesive for patching up small punctures. As a bonus, this Smart Kit contains instructions with an adhesive backing that serve as an emergency tire boot, should you rip a bigger hole in your sidewall. Other included items include a stainless steel scuffer and two Power Levers for dealing with difficult tire beads.
