Micro-sized tubeless repair and inflation kit containing an advanced 2-in-1 CO2 injector head that repairs a puncture and inflates a tubeless tire in one step with massive air or can simply be used as a traditional CO2 inflator through the valve stem. The inflator head is compatible with both Presta and Schrader valves and the included mounting strap attaches to the seatpost or frame and can carry one or two 25g CO2 bombs. This set is without the bomb.
