Air Tool MTB Pump – One Size

The Air Tool MTB pump is a dependable and durable big-volume frame pump designed to be carried on the bike for use in all off-road conditions. It features a new inverted design that greatly increases air capacity, reducing pump time by up to two minutes. The inverted dual chamber design is smaller yet moves 28% more air per stroke compared to the previous design. A twist locking head is easily converted to fit both Presta and Schrader valves, making it compatible with most bike tire types. The machined outer barrel provides extra grip while pumping, and the all-aluminum inner and outer chamber ensures durable performance in demanding conditions. The pump comes with a water bottle boss frame mounting bracket for convenient on-bike storage. An updated dust cover prevents unwanted opening, keeping the pump clean and ready for use.
