Road 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. Designed for the high performance road rider, the HybridRocket HP lets you quickly rejoin the group after fixing a flat. The mini-sized pump and integrated CO2 inflator lets you choose between pumping, inflating with CO2 or a combination of both. Its CNC aluminum barrel is optimized for high pressure and inflates up to 160 psi / 11 bar. An extendable hose with SmartHead® ThreadLock accepts Presta and Schrader valves. Note : Use the PCT Cap to tighten or remove two piece Presta valve cores when necessary. * Use only Topeak 16g CO2 cartridges.
