The ABS-1 Pro floor pump chuck features a 90° design for enhanced function and usability. The highly durable construction is built using machined aluminum and Composite Matrix materials with an extremely robust brass swivel that offers ultra-smooth articulation. The chuck quickly “flips” to allow for direct threading onto either a Presta valve core or directly to a threaded Presta shaft (with the valve core removed).

A Presta valve-core wrench is integrated into the backside of the chuck head and completes the system, providing easy valve core tightening or removal.
