How reliable is a pressure gauge which is incorporated into a pump ?
I suppose it depends on the pump manufacturer and how good they are, my pump was 50€ (sale price 30€) so I assume its a reasonable one, it´s a floor standing one you pump down onto whilst holding it with your feet, pressure gauge is a standard round clock face type with PSI and both Presta and Schrader (My 700c x 37 tyres are Presta).
Is it worthwhile getting a stand alone pressure gauge ? Anything recommended ? Maybe digital is better for this type of thing, and accuracy ?
