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 Mini lets you quickly rejoin the group after fixing a flat. The extra compact pump and integrated CO2 inflator lets you choose between pumping, inflating with CO2 or a combination of both, and once you're finished, it fits neatly in your jersey pocket.
