Review on 🚴 LEZYNE ABS-1 Pro Chuck Bicycle Valve Head: Presta & Schrader Compatible High Performance for Your Bike by Kevin Zamora

After a few years I had problems with the original ABS-2 cartridge that fitted my Lezyne floor pump. This cartridge appears to seal better on various tubeless valve stems that are far from a uniform diameter, particularly those supplied by manufacturers in the Far East. As with any threaded cartridge, care must be taken not to twist the valve core. All in all a good cartridge on the regular Lezyne Premium. Like many other Lezyne products, they have a set of o-rings that will loosen over time, wear out and require maintenance.
