Pressure tuning for Presta and Schrader valves.

The Lezyne ABS-2 Chuck is an innovative chuck attachment for Lezyne's line of high-pressure floor pumps. It quickly and securely attaches to both Presta and Schrader valves for maximum convenience, bleeding out excess air and fine-tuning pressure with its Air Bleed System (ABS) button. The 90-degree bend works with disc-equipped mountain bikes, as well as aero rims on time trial and road bikes. Plus, its knurled aluminum locking sleeve and rugged composite body ensure longevity throughout multiple seasons of use.

This chuck worked out great on my Alloy Drive floor pump. The red is for high pressure pumps (generally road bikes) and the orange is for high volume (generally mountain bike) pumps. Innovative design allows you to use the chuck with a Presta or Schrader valves easily.

Will this fit previous generations of Lezyne floor pumps like the Lezyne Classic Dirt Floor Drive Pump?
