This ABS1 PRO HP is an innovative high pressure ABS chuck for Presta or Schrader valves. Upgraded and redesigned, 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 aluminium 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.
