Specialized 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.

• 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
