I use this for my Presta valves on my road bikes. It delivers reliable results and holds the print once removed, eliminating the need for weird head angles when checking the print. I use it to check the pressure before every ride, but it's light enough to justify using it on longer rides where I want to make sure I have the least rolling resistance after a flat without overrunning (generally 130-pound tires hold square inches when on slippery roads)
