Why Should You Choose the ZN40 52mm Zinc Bearing for Your Build?

The Cane Creek ZN40 52mm Zinc Plated bearing is the go-to individual replacement for the lower cup on standard threadless headsets. Built with a zinc-plated machined steel race and hardened steel balls, this cartridge bearing resists corrosion and maintains consistent steering performance through wet rides, variable weather, and high-mileage seasons. The zinc coating provides meaningful protection over uncoated alternatives, extending service intervals and keeping your headset feeling dialed longer.

At 52mm, this bearing integrates cleanly into the lower cup of a wide range of road and gravel headsets, with confirmed compatibility across Cane Creek 110-, 40-, and 10-Series headsets. When your lower bearing shows wear while the upper is still serviceable, this single replacement lets you address the problem precisely without swapping components that have life left in them. Riders who log serious mileage in the Pacific Northwest or any wet-weather region will appreciate the corrosion protection built into every ZN40 bearing.

FAQ

Is this a single bearing or a kit?

This is a single 52mm bearing. If you need both upper and lower bearings, consider the ZN40 Bearing Kit which includes both in one purchase.

What position does a 52mm bearing typically fill?

The 52mm size most commonly seats in the lower cup of standard external or semi-integrated headsets. Check your headset documentation or measure your current bearing to confirm fitment.

What does zinc plating actually do for a headset bearing?

Zinc plating forms a sacrificial corrosion barrier over the steel race. It slows rust formation when exposed to moisture, road spray, and humidity, extending the usable life of the bearing compared to bare steel alternatives.

Best For

Road and gravel riders replacing a worn lower headset bearing on Cane Creek 110, 40, or 10-Series headsets. Particularly well-suited for cyclists in wet-weather regions who want corrosion resistance without moving up to a premium sealed bearing.
