Available as a spare part, the The Lezyne ABS-1 Pro Chuck has been upgraded and redesigned to offer you even greater functionality. It features a highly durable construction and can be used on both Presta and Schrader valves by easily unscrewing and flipping the chuck. It threads onto valves for superior engagement and even has an integrated Presta valve core remover for tubeless systems.

Who's this item for: Riders after a replacement chuck for their Lezyne Alloy, Classic, or Digital Over Drive pumps.

Materials: Made from a combination of machined aluminium, composite materials, and a brass swivel, it is extremely durable.

Rated pressure: This is the high pressure version.

Pump head type: It has a thread on valve for better engagement. The 90 degree design makes it even easier to use.

Air Release: The ABS-1 Pro chuck has an air release button but note that this functions differently depending on what type of valve is being used.

• Schrader: Allows for an infinite release of air to fine-tune the tyre pressure.
• Presta: Releases air from the hose to aid with removal without unscrewing the valve core. Does not allow for the fine-tuning of air pressure when used with Presta valves.

What valves does it work on: This can be used on both Schrader and Presta valves.

Pros: Threaded engagement means little chance of leakage, the 90 degree angle makes it easy to use, and it is made of durable materials.

Cons: You do have to unscrew and re-screw in the chuck for different valves. Can't use the air release button to fine-tune air pressures when used with Presta valves.
