The 40-Series sets the standard for performance, durability and value. Drawing from the Premium 110-Series Design, the 40-Series incorporates all the features necessary for a durable, light-weight, long-lasting headset. The new ZN40 bearings are a zinc-coated, machined steel cartridge bearing with hardened steel balls. The new material is much more corrosion-resistant, which vastly increases the longevity of the 40 series headsets.
