Big tires need a big pump. Luckily, Lezyne's Alloy Dirt Floor Drive Pump features an oversize barrel and shaft to push double amount of air of a standard pump—enough to seat a tubeless tire! It's built to last with a durable CNC'd aluminum barrel and base, and the tight-sealing Flip-Thread head fits both Presta and Schrader valves. You'll also appreciate the extra-long hose, varnished wooden handle and easy-to-read gauge.
