Lezyne ABS-1 Pro Tubeless Chuck Head Black Pump Accessories

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. Compatible with other Lezyne ABS chucks.
