The Over Drive's big supplemental can is manually inflatable by toggling a foot lever. When it's full, pop the lever, throw some shade at your sealant, and hope that your frame actually does have clearance for the new tires. You can also bypass the high-pressure can and use the pump as a regular floor pump while not trying to pin down those evasive beads. Though it's a given with Lezyne, the pump's high-quality construction of steel and alloy warrants a call-out. The pump feels stable and solid--no rickety plastic base or wobbly piston/chamber interface. Even the hose is reinforced with a braided nylon sheath, giving it more durability (ostensibly to handle the additional PSI) but also--and more importantly--making it look really, really cool. Many of us leave our bikes in the front room because we figure they're as much a work of art as anything else we could display in there; Lezyne makes one of the only pumps that we've give similar pride of place to. This particular iteration of pump genius is finished with Lezyne's ABS1 Pro chuck at one end and a precise, digital gauge at the other. The ABS1 Pro slips effortlessly onto both Presta and Schrader valves (if you're pressing hard, you're doing it wrong) and the digital gauge keeps you abreast of PSI up to 220 without making you estimate where exactly the quivering little arrow is pointing.
