There are a couple of things that set this tire gauge apart for me. First, it makes 0-160 psi. Most of the time I inflate car tires to around 30psi, but my wife has a road bike with tires that need around 115psi so I can use this gauge for everything. Another thing I'm very happy with is that it comes with replaceable cartridges, one of which is for the Presta valves that most road bikes seem to have. I couldn't find a Presta cartridge anywhere except for one or two that look pretty crappy. The one supplied with this gauge is high quality brass. It also comes with a regular car tire liner and a dual angle truck tire liner. What I really want now is to be able to use a Presta cartridge to inflate bike tires instead of just measuring them. It would also be nice if I could use any cartridge with a pressure gauge. Unfortunately the cartridge thread is not the usual 1/4" NPT thread. I took the gauge to a hardware store to find out what it was and it appears to be a 1/8" NPT thread. I ordered several adapters from Revain to see if I could get everything the way I wanted. enough to do it. Excellent customer service.
