Upgraded and redesigned for Year 11, the ABS1 Pro further advances Lezyne's classic Flip-Thread Chuck system. It 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 and fluid brass swivel. The chuck quickly “flips” for Presta or Schrader valves and threads on for superior engagement. An integrated Presta valve-core wrench completes the system, providing easy valve core tightening or removal for tubeless systems.

• Pump chuck for Presta and Schrader valves
• Durable materials are made to last
• Integrated Presta valve core wrench is always where you need it
