Tire pressure is one of the most important things to get right on your bike. It's also free once you have a pump, so why not do yourself a favor and take the big step to get it exactly right every time. Now, more than ever, Lezyne has mad this possible. The CNC Digital Drive Pump takes the guesswork out of getting your air pressure exactly right with an easy to read digital readout. Battery life won't be an issue. The Digital Drive's battery lasts about a year and warns you well in advance if it's getting low. Other than the slick digital readout, the CNC Digital Drive is built just like Lezyne's other high quality floor pumps. It features CNC machined precision construction, Lezyne's ABS Flip Thread chuck, an easy release system, and a Speed Chuck for special applications where a 90 degree head is required.
