Tyre pressure is a significant determinant of a road bike's performance. Too high and you will get a stiff ride and there's the risk of skidding or even a tyre exploding on long downhills. Too low and the bike will handle sloppily and you may get tyre roll or risk pinch flats. So it's useful to be able to measure your tyre pressures accurately. It's also important off road, where grip on loose surfaces can be critical and you don't want to bottom out on a wheel rim.

The Topeak SmartGauge D2 pressure gauge digitally measures pressures up to 250psi in 1psi increments, allowing you to accurately measure and tune pressures in tyres with Presta or Schrader valves, or in shocks for the off-road minded. It’s easy to use: just switch on, push onto the valve and wait until it beeps, with the reading being displayed even once the gauge is taken off the tyre.
