Filling a tire after a day on low pressure can take longer than the trail did. The APEX Rapid Inflation Valve is built for fast air-up: a large shop compressor at 120 PSI and 10 CFM can fill a 37 to 39 in tire in under 10 seconds. Install it in a dual valve-stem wheel and air-up stops being a chore.
