X.O. stands for extraordinary -- the only way to describe this newest CNC machined alloy JoeBlow™ floor pump. An elegant yet modern representation of the classic floor pump, the JoeBlow X.O.'s construction -- from its wide stable base to its smoothly shaped handle -- is precisely machined and beautifully polished aluminum alloy. Its smooth action and long stroke powers up to 200 psi / 14 bar to fill even the highest pressure track tires. To make tire inflation simple we've added our SmartHead™ ThreadLock hose head which fits Presta and Schrader valves. The machined aluminum base ads maximum stability and an extra-long braided metal hose easily reaches bikes mounted in the workstand.
