Tubeless-specific chuck “flips” to allow for direct threading onto either a Presta valve core—for easy top-offs and pressure adjustments—or directly to a threaded Presta shaft (with the valve core removed) in order to provide more airflow for seating tubeless tires. Precision machined aluminum.
Technical Specs
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.
