I carry a co2 road kit and a spare tube just to get me home or to the car. I have a Kobalt portable compressor in the car and a small tool kit at all times in my vehicle. It has a small detachable digital meter that fits in my seat bag with the kit and tube if I want to take it. Also has attachements for different stems/valves. One of the best tools I have bought for $30 from lowes. I am still considering a frame pump, but not in a hurry to buy one.
