A micro-sized tubeless tire repair and inflation kit featuring an advanced 2-in-1 CO2 injector head that repairs a puncture and inflates the tubeless tire in one step with massive air or can simply be used as a traditional CO2 inflator via the valve stem. The inflator head is compatible with both Presta and Schrader valves and the included mounting strap attaches to seatposts, saddle rails, or frame tubes and can carry one or two threaded 25g CO2 cartridges.
