You know those things you attach to your valve stem on your car tires that tells you when the pressure is low? It has these red, yellow, and green bands.
I am looking for a similar thing for presta valves, but preferably very sensitive in the pressure range I am interested in. I like to run my rear tire around 23-25 psi, but I notice that the rolling resistance starts to go up when it gets to around 20 psi. So I would like if it had a sensitivity of at least 2 psi in this range.
