Why We Like The Performance ZS56/40 Lower Headset Assembly

We use the Performance ZS56/40 Lower Headset Assembly to maintain our Wolf Tooth Headsets once they become worn out. The oxide steel bearings provide a long life of buttery smooth functionality, while the aircraft-grade aluminum body finds the balance between lightness and durability.
