Smaller, more efficient, reliable—three features of the new Air Tool MTB Mini pump. With the new, inverted double-chamber design, this pump moves more air than the unit it replaced, even more efficiently. Best of all, it’s now available with a frame mounting bracket to keep it out of your backpack or pocket and easily accessible on your bike.

• Inverted, double chamber design is smaller yet increases the air handling capacity by 20% when compared to our previous design, reducing pumping time by up to two minutes.
• Twist locking head reduces size and can be easily converted to fit Presta or Schrader valves.
• Machined outer barrel for extra grip while pumping.
• Aluminum inner and outer chamber for durable performance.
• Max pressure: 60 PSI (4.1bar)
• Volume-per-stroke: 55cc
• Water bottle boss frame mounting bracket included.

Occasionally, without notice, manufacturers change product design and/or specifications.
