PURCHASE LOCALLY - Lezyne Macro Floor Drive Pump
$59.99
We have long recommended Lezyne brand pumps, but due to recent drastic increases in shipping costs, it is more economical for you to purchase them locally or through Amazon directly (if you have free prime shipping).
Unfortunately, Lezyne makes a dizzying array of pumps (no idea why they have so many options) but what you want is the ABS Flip Thread Chuck (yellow fitting) or the ABS1 Pro (red 90° fitting). Avoid thier much larger "Dual Valve Head" design.
