The ABS1 Pro Pump Head from Lezyne is a flip-thread ABS chuck that’s compatible with both Presta and Schrader valves. Constructed of machined aluminum and composite matrix materials, this chuck is exceptionally robust. A fluid brass swivel further augments its durability for long-lasting integrity. Lezyne’s flip-thread system allows the chuck to “flip” for threading to either Presta or Schrader valves. Its 90° angle provides improved function and usability while an integrated Presta valve core wrench ensures easy core tightening and removal with tubeless setups.

    Slow to switch between presta & schrader but solid connection

    I replaced an ABS-2 head with this new one and like it quite a bit. The ABS-2 has a goofy spring inside that decided to destroy itself, this new design has no springs and fewer o-rings so I'm happy. You unscrew and flip the end to switch between presta and schrader valves, which is a little annoying, but it only takes a few seconds (same as the Micro Floor Drive XL). I don't know how useful the valve core wrench will be but it's a harmless addition, so I like it. Overall I like Lezyne's pumps and this new pump head doesn't disappoint.
