What Makes the ZN40 41.8mm 36x45 the Precision Choice?

The Cane Creek ZN40 41.8mm 36x45 Headset Bearing is the correct spec replacement for integrated headsets with a 36-degree cup contact angle, a configuration that requires exact matching to function properly. The zinc-coated cartridge construction protects against corrosion from moisture and road contamination, while hardened steel balls maintain smooth steering rotation under the sustained loads that headset bearings face every ride. On an integrated headset, bearing quality directly determines the quality of your steering input, and the ZN40 is built to hold that standard.

The 41.8mm outer diameter is a common bearing size in integrated and zero-stack headset designs, and this ZN40 is cross-compatible with Cane Creek 110-, 40-, and 10-Series headsets calling for this spec. If you are experiencing play, roughness, or creaking that persists after checking bolts and preload, replacing the bearing at this position is the likely fix. Keeping a ZN40 on hand is the move for any rider who services their own bike and prefers not to discover a missing part when they are ready to ride.

FAQ

What is the difference between the 41mm and 41.8mm ZN40 36x45 bearings?

The 0.8mm difference is a real dimensional variation that matters for proper fitment. These sizes correspond to different headset cup seat standards. Measure your existing bearing outer diameter precisely before choosing between them.

Which headset series typically uses a 41.8mm 36x45 bearing?

The 41.8mm 36x45 configuration appears in zero-stack and integrated Cane Creek headsets used on many modern road and gravel frames. Reference your specific headset model documentation or contact Cane Creek directly if unsure.

Should I grease a replacement headset bearing before installing?

The bearing itself comes factory greased and sealed. However, applying a thin layer of grease to the outer race contact surface in the cup can help prevent corrosion between the bearing and cup, and makes future removal easier.

Best For

Cyclists with modern road or gravel frames using Cane Creek integrated headsets that require a 41.8mm 36x45 bearing. A natural choice for riders who do their own maintenance and want the right OEM-spec bearing ready before wear becomes a problem.
