Mini Pumps

Designed for Fat and Semi Fat tire bikes, the Big Bore packs massive volume per stroke and a unique head that still works with winter gloves on - Oversized press-on Schrader and Presta head won't accidentally remove valve cores and can be easily used with thick gloves. - Flexible hose attachment allows for aggressive pumping without fear of damaging valve stems. - Inverted barrel design allows for high volume in a compact size. - Coarse machined aluminum barrel for extra grip. - Water bottle boss mount with elastomer band included. - Max pressure: 50psi (3.5bar) - Volume per stroke: 90cc

Small, efficient, reliable—the three key features of the Air Tool MTB Mini pump. With the inverted dual chamber design, this pump moves 20% more air per stroke than the unit it replaced, yet is 10% smaller. - Inverted dual chamber design is smaller yet moves 20% 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. - Aluminum inner and outer chamber for durable performance. - Water bottle boss frame mounting bracket included. - Max pressure: 60 PSI (4.1bar) - Volume-per-stroke: 55cc - Water bottle boss frame mounting bracket included.
