X.O. stands for extraordinary – the only way to describe this 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 adds maximum stability and an extra-long braided metal hose easily reaches bikes mounted in the workstand. Note : ThreadLock pump head should be used with caution on do removable valve core type Presta inner tubes and tubular tires as the valve core may be inadvertently removed when unthreading the pump head. To reduce the possibility of accidental removal of the valve core, ensure ThreadLock is installed and removed correctly and in line with the valve stem.
