Air Tool MTB Pump

The Air Tool MTB pump is our most dependable and durable big-volume frame pump. It's intended to be carried on the bike for use in all off-road conditions. You'll find that it features a new inverted design, so it greatly increases air capacity, which reduces pump time by up to two minutes. Inverted dual chamber design is smaller yet moves 28% more air per stroke when compared to our previous design, reducing pumping time by up to two minutes. Twist locking head is easily converted to fit Presta or Schrader valves. Machined outer barrel for extra grip while pumping. All-aluminum inner and outer chamber for durable performance. Water bottle boss frame mounting bracket included. Updated dust cover prevents unwanted opening. Max pressure: 60 PSI (4.1bar) Volume-per-stroke: 100cc
