The Micro Floor Drive XL is a portable hand pump with floor pump capabilities developed to efficiently inflate fat bike tires. It features a CNC-machined aluminum construction, which keeps its weight to a minimum without sacrificing durability. An extra-large, high-volume barrel produces large amounts of air with each pump and can inflate tires up to 35 psi (2.4 bar). A long, integrated hose and a stainless steel foot peg improves pumping efficiency and reduces trailside downtime. The ABS Flip Chuck is compatible with both Presta and Schrader valves and threads into the pumps base for optimal storage.
