HybridRocket RXRoad mini pump, CO2 inflator, or both. The choice is yours! HybridRocket technology combines the reliability of a mini pump with the rapid tire filling ability of a CO2 inflator in a single unit. The smallest in the HybridRocket Series, the HybridRocket RX lets you quickly rejoin the group after fixing a flat. The micro sized pump and integrated CO2 inflator lets you choose between pumping, inflating with CO2 or a combination of both. Its butted aluminum barrel is optimized for high pressure and inflates up to 160 psi 11 bar. An extendable hose takes stress off the valve stem while pumping. Use only Topeak 16g CO2 cartridges.
