What Sets the ZN40 47mm 45x45 Bearing Apart from the Rest?

The Cane Creek ZN40 47mm Headset Bearing is a precisely engineered replacement for headsets requiring a 45x45-degree contact angle configuration. Built with a zinc-coated steel race and hardened steel balls, this cartridge bearing delivers corrosion resistance and smooth rotation through extended mileage in demanding conditions. The 45x45 contact geometry provides solid axial load handling, keeping steering precise and play-free whether you are hammering gravel or pushing pace on a road loop.

The 47mm diameter targets a specific bearing seat size found across Cane Creek 110-, 40-, and 10-Series headsets, ensuring a clean, accurate fit without adaptation. If your current bearing is showing roughness, visible wear, or corrosion, swapping in a ZN40 is a fast, affordable fix that restores full steering performance. This is the bearing for riders who maintain their own equipment and refuse to ride on compromised components.
