The Lezyne Alloy Drive Floor Pump puts lesser pumps to shame with its timeless aluminum construction, brilliant anodized finish, and high pressure output. The pump's 220PSI output ensures proper inflation of both road tires and mountain bike tires, with a 90 degree valve design that allows it to easily work with disc equipped wheels. Its ABS 2 Flip Thread Chuck valve design makes swapping between Presta and Schrader valves simple and intuitive, even on aero disc wheels, while Lezyne's Air Bleed System ABS lets you incrementally dial in pressure to precise levels on both valve types by removing air slowly. And with the oversized 3. 5in pressure gauge, you'll never have to squint at or second guess air pressure levels again.
