The Lezyne Sport Gravel Drive Floor Pump is specially designed for gravel bikes and other mid-volume tires. Constructed from a larger diameter barrel than Lezyne's classic Floor Drive pumps, the Sport Gravel pushes more air, for faster fill ups. An easy-to-read and very accurate analog gauge lets you dial in the perfect pressure while an extra-long hose makes filling up easier whether it's on the ground, stand or hanging on your bike rack. The pump comes with Lezyne's Tubeless Chuck allowing you to seat tubeless tires and pre-ride top-offs. Built to last, the Sport Gravel Drive is a great pump to have.
