Don't forget to adjust your SAG. The digital display and zero-loss air valve offer the most accurate pressure data for setting sag on air-sprung forks and rear shocks. No need for a measuring tape or ruler - the body of the pump is laser etched for precise indication when setting sag. Setting sag is the most crucial step in setting up an air-sprung suspension product. Take control of your air pressure with the new Double Barrel Air pump from Cane Creek.
