Replacement head only, for CNC Tubeless Drive, Sport Gravel Drive, Gravel Digital Drive and Gravel Digital Drive Pro. Presta/m6x0.8

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” for Presta or Schrader valves and threads on for superior engagement.

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.
