A lot has been made recently about bicycle pumps and the ability of their gauges to be accurate at low pressures. Most tend to maintain the highest level of precision at pressures well above where the average fat bike, cyclocross bike, or even mountain bike is run. One or two psi off might not seem like much, but when you’re only running 10 psi, up to 20% variance is a big deal.
Apparently, when Brady Kappius isn’t busy rethinking bicycle hubs and designing complete wheels, there is enough time to come up with gems like his new Digitial Pressure Gauge. Available in 3 varieties, the Gauge will be sold in Fat Bike, Cyclocross/Low MTB, and Cyclocross/MTB pressure ranges. The Fat Bike model will measure from 0-15 psi with 0.01 psi resolution, then 0-30 psi also with 0.01 psi resolution for the Cyclocross/Low MTB option, and finally 0-50 psi with 0.02 resolution for the Cyclocross/MTB gauge all with a +/- 1% accuracy.
Each gauge is for presta valves only and includes a bleeder valve so you can pump up the tire past the desired pressure, then bleed it down to the precise number. Powered by an included 9v battery, the gauge has a 20 minute auto off feature, and each model has a pressure limit that is twice the intended pressure range (so don’t use the fat bike model on your road bike!). Available for pre-order currently on the Kappius store, each gauge will run $159.99 with your choice of units and will look slightly different than the early prototype gauge above.
