What Makes the ZN40 Bearing Kit Your Best Headset Upgrade?

The Cane Creek ZN40 Series Bearing Kit takes the guesswork out of headset service by pairing both upper and lower bearings in one package. These zinc-coated cartridge bearings feature hardened steel balls and precision-machined races built to handle the demands of serious road and gravel riding. The 45x45 contact angle delivers smooth, responsive steering that stays dialed across seasons of mileage and variable weather exposure.

The 42/52mm sizing covers the most common bearing configuration found on modern road and gravel headsets, with full cross-compatibility across Cane Creek 110-, 40-, and 10-Series headsets. Replacing both bearings simultaneously ensures matched performance, prevents accelerated wear from mixing old and new components, and restores the precise, creak-free feel that a quality headset demands. This kit is the clean, efficient solution for riders who want their front end feeling factory-fresh.

FAQ

What headsets are compatible with this ZN40 42/52mm Bearing Kit?

This kit fits Cane Creek 110-, 40-, and 10-Series headsets using a 42mm upper and 52mm lower bearing. Always confirm your headset model and bearing seat sizes before ordering.

Should I replace both headset bearings at the same time?

Yes. Mixing worn and new bearings creates uneven load distribution and accelerates wear on the new component. Replacing both simultaneously ensures matched performance and extends service life.

How do I know when my headset bearings need replacing?

Look for notchy or gritty steering, persistent play that preload adjustment cannot fix, or visible pitting on the bearing surfaces. If it feels rough, it is time for fresh bearings.
