Overview
Is the ZN40 38mm Zinc Bearing the Precision Fit You Need?
The Cane Creek ZN40 38mm Zinc Plated bearing handles the smaller-diameter upper cup positions found on certain road and gravel headsets, delivering the precision and durability you expect from a quality replacement component. The zinc-plated cartridge construction provides a corrosion-resistant barrier against moisture and road spray, while hardened steel balls maintain smooth, reliable rotation through demanding mileage. Upgrading to a ZN40 at this position means fewer maintenance headaches and a consistently crisp steering feel.
This 38mm bearing is compatible with Cane Creek 110-, 40-, and 10-Series headsets that call for a smaller upper bearing, making it a precise replacement for worn or corroded components in those configurations. Notchy steering that cannot be resolved by preload adjustment often points directly to bearing wear, and a fresh ZN40 typically resolves it immediately. A go-to part for riders who wrench their own bikes and want the right component on the shelf before it becomes an urgent mid-season fix.

FAQ
Good questions
Get to know Cane Creek
There's more to Cane Creek than this one product. Our Cane Creek page has the full Cane Creek lineup we carry and more about the brand.
Visit the Cane Creek page →What position does a 38mm bearing typically occupy?
The 38mm size is typically found in the upper cup of external or semi-integrated headsets on certain road and gravel frame geometries. Confirm by measuring your existing bearing or referencing your headset documentation.
Can I use a ZN40 bearing to replace a different brand bearing of the same size?
Bearings are standardized by outer diameter, inner diameter, and width. If your existing bearing matches the 38mm outer diameter and the other dimensions align, a ZN40 will work. Always verify all three dimensions before replacing.
How long should a quality headset bearing last?
Service life depends heavily on riding conditions, maintenance frequency, and whether the headset is properly preloaded. In normal road riding with regular service, quality cartridge bearings typically last one to several seasons.
