The Efficient Velo Tools Bleedin’ Gauge is known as “The Rolex” by racers, coaches, and the national team staff of many nations.
Every rider/tire/condition combination requires a custom tire pressure solution for the best results. Bleedin’ Gauges dial it in with repeatable accuracy. Inflate high and bleed off to the precise number desired. They’re unaffected by temperature, a fully-serviceable cotton filter protects the mechanism from sealant, and there’s no batteries to die or screens to break. If you’re someone to whom 1/2 of a PSI makes a real difference, you need a Bleedin’ Gauge!
Or just use it to see how far off your floor pump really is.
Available in 5 pressure ranges (in PSI): 0-15, 0-30, 0-60, 0-100, and 0-160. Accuracy is highest in the middle of the dial’s range (but it is also very accurate at the edges too). Choose accordingly.
