Product Details

Specialized Air Tool Big Bore Pump

This super high volume pump for fat tyre bikes delivers 90cc per stroke - that's twice as much as a regular mini pump - thanks to its ingenious reversed barrel design where the pump's barrel is wider diameter than its plunger handle.

The Specialized Air Tool Big Bore Pump is therefore especially suitable for 27.5-plus and fat bikes.

  • The machined aluminium handle and barrel are textured to offer a better grip when the weather turns bad - even when you're wearing thick gloves.
  • Twinhead push-fit design - one side of the head is for Schrader, the other for Presta valves.
  • Each pump head is extra deep to reduce the risk of accidentally removing or bending the valve core.
  • Another first from Specialized, they now publish how much air volume their pumps deliver per stroke. In this case: 90cc.
  • Max pressure: 50psi (3.5bar) - optimised for fat tyre mountain bikes.
  • 155g - based on weighing the Specialized Air Tool Big Bore Pump on its own at Bike Co-op HQ in December 2015.
  • Supplied with bottle cage boss bracket and bolts (you'll need a 3mm Allen key to fit this bracket) weighing 23g.
  • Inflates up to 30 psi (after all, this is a pump for a fat bike you might run at around 12 psi).
  • 20 cm / 8 inches long - fits in back pocket or backpack.
