Mountain 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 mountain bike rider, the HybridRocket MT lets you quickly get back on the trail 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 CNC aluminum barrel is optimized for fat tires and inflates up to 90 psi / 6 bar. An extendable hose with SmartHead™ ThreadLock accepts Presta and Schrader valves.
