A well-dialed suspension system is key to happy trails. Too soft, and the bike will be a sloppy, floppy mess; too firm, and it'll bounce you up and down like your childhood pogo stick. FOX Racing Shox's Digital HP Shock Pump brings the power of science to your steed, letting you fine-tune your shocks with a little help from the modern design. The digital display measures in 0. 5-psi increments up to 100 psi, and 1-psi increments above 100 psi, with the ability to read up to 300 psi. Overfill your shocks and a handy bleed button allows you to remove air so you can hit that sweet spot.
