Air Force Tier 2 Big (Gauge) Floor Pump

The Perfect pump for High-Volume / Low-Pressure Tires. 

For Mountain and Gravel Bikes a more comfortable ride equals faster speeds.  Finding the optimal tire pressure is a critical step to get the most performance out of your bike. 

The New Tier 2Big floor pump features an oversized 4 inch 2 stage gauge that reads 1 PSI increments from 5-35 PSI and 5 PSI increments from 35-140 PSI.  

When you ride low pressure tires you'll feel a world of difference between 20-25 PSI and you'll want to get it right.

The Tier 2Big provides the accuracy of a digital gauge for those running low tire pressures without requiring the high price tag or batteries.

The high efficiency of the Tier 2Big will easily fill a road tire and maxes out at 140 PSI.
