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.

Sensible design runs throughout. The double-headed end makes swapping between Presta and Schrader valves effortless and should enjoy better longevity than the “Smart head” type. No rebuild kit is available at time of review but outside of a workshop environment it's not a reason not to buy. A clever release pin allows judicious bleeding in the event of over-inflation and unlike some the unit doesn’t automatically reset itself, nor could it be cajoled into wildly inaccurate readings.

The rubberised exterior gives a positive grip, and gives insulation from shock and accidental drops. Our test unit has survived falling from a jersey pocket whilst riding at full pelt and the usual accidental workshop carelessness with only slight scuffing to the casing. Robust construction and anecdotal experience is reinforced by Edinburgh Bicycle who confirm they’ve sold hundreds in the past two years without a single return.

Every cyclist should have a good quality, separate gauge and Revolution represents superb value for money. The only possible improvement would be a backlight for those late night flats in the back of beyond.

Verdict

A well designed gauge at a great price
