Accurate enough for workshop duties, yet compact enought to slip into the smallest of seat packs or jersey pockets, the SKS Air Checker is the best digital tyre pressure gauge I’ve used to date, but isn’t perfect.
Powered by CR type battery and weighing a mere 60g it scores over other designs by virtue of light yet solid construction.
Revolution’s air pressure gauge takes the guesswork out of optimum tyre inflation. Small enough to sneak inside a jersey pocket, yet sturdy enough for the workshop, it’s blessed with the largest and clearest display I’ve encountered. Registering pressure (in both PSI and Bar) from zero to a whopping 260psi – enough to blow a tubular clean off the rim – I can’t imagine a situation (other than puncturing by the roadside without a pump) where it wouldn't come in handy.
