The Lezyne ABS-1 Pro Tubeless Chuck is a premium pump head upgrade designed specifically for modern tubeless setups and high-volume tires. Built from durable, precision-machined materials, it delivers a secure, airtight connection to your valve so you can inflate confidently without annoying leaks or blow-offs. Its design is compatible with Presta valves, including those used with tubeless systems, making it ideal for mountain, gravel, and road bikes alike. Whether you are topping up pressure before a ride or seating a stubborn tubeless tire, this chuck helps you get the job done quickly and efficiently.
Featuring Lezyne’s proven ABS (Air Bleed System) technology, the ABS-1 Pro Tubeless Chuck allows you to fine-tune pressure by releasing excess air with a simple bleed function, especially useful when working with high pressures or sensitive tire setups. The secure locking mechanism helps prevent accidental disconnection, while the angled design offers better access in tight spaces, such as deep-section rims or crowded workshop areas. Upgrade your floor pump with this chuck to enjoy smoother, cleaner inflation sessions and a more reliable seal every time you work on your tubeless wheels.
