The ROCKBROS JG-PB-11 is a compact manual mini pump designed to keep your tires inflated during rides on road, city, or mountain bikes. Crafted from CNC machined aluminum alloy, this tool weighs only 67 g and measures roughly 13.5 cm in length, making it easy to carry without adding bulk to your gear. Its oxidation-resistant finish ensures durability against the elements while you are on the road. Equipped with a dual universal head, the pump is compatible with both Presta and Schrader valves. A built-in lever locking system creates an airtight seal to ensure efficient air delivery up to a maximum pressure of 130 PSI. For convenient transport, it comes with a mounting bracket and strap, allowing you to secure it firmly to your bike frame for quick access whenever you need it.
