A portable hand pump developed for fat bike, plus bike and high volume tyres. The Micro Floor Drive XL is a portable hand pump with floor pump capabilities developed to efficiently inflate high volume tyres. It features a CNC-machined aluminium 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 shrader valves and threads into the pumpa s base for optimal storage.
