No gauge for me. I'm fortunate in that a 16g cartridge will fill a 700x23 tire to around 120-130psi, right where I need it for my size. OTOH, I'm not sure about how it would work with the 406xsomething Marathons on my folder. Having a trigger on the inflator, and fingers for a "pinch test" will have to do, I suppose. Anyhow, those Marathons are amazingly flatproof so I'm not too worried about it being a common problem.
