Just how important is it to set your tyres to the right pressure? According to Wil, it is VERY important, and it can make a huge difference to how your bike rides on the trail. In a quest to find the best tool for the job, Wil and the gang have tested out six different tyre pressure gauges. Next up is the Digital Check Drive from Lezyne. The newest gauge on test here, the Digital Check Drive is, perhaps surprisingly, Lezyne’s first standalone pressure gauge. Known for producing a huge range of pumps, tools, lights and GPS computers, Lezyne has been doing the digital pressure thing for a wee while now, with a digital readout integrated into some of its floor and mini-pump models, as well as the brilliant Digital Shock Drive that won a Singletrack Recommended Award. Taking that same technology and packing it into the compact, pen-shaped Digital Check Drive, Lezyne now has a purpose-built tyre pressure gauge. Since it uses the same mechanism as Lezyne’s own shock pump, the Digital Check Drive will measure up to 350psi – perhaps a little over the top for mountain bike tyres. Despite its enormous upper limit though, Lezyne states the gauge is accurate to +/- 1 psi across the entire 0-350 psi range. Certainly in our testing at pressures between 15-25 psi, the Digital Check Drive proved to be highly accurate, and just as good as the EVT and Fabric gauges. A small rubber button turns the gauge on or...
