Is the ZN40 42/52mm 36x45 Kit Right for Your Headset?

The Cane Creek ZN40 Series 42/52mm 36x45 Bearing Kit delivers both upper and lower integrated headset bearings in a single package, matched and ready to restore your headset to full performance. These zinc-coated cartridge bearings provide a corrosion-resistant barrier against road spray and wet conditions, while hardened steel balls ensure consistent, smooth steering rotation mile after mile. Buying both bearings together as a kit guarantees matched components and removes the risk of running a worn bearing alongside a fresh one.

The 42mm upper and 52mm lower pairing targets integrated headset designs requiring the 36x45 contact angle, and is cross-compatible with Cane Creek 110-, 40-, and 10-Series headsets that specify this configuration. This kit differs from the 41/52mm version by one millimeter in the upper bearing, a dimension that matters for a correct press fit. If you are unsure which kit applies to your headset, measure the outer diameter of your existing upper bearing before ordering. For the rider with a full headset overhaul on the schedule, this kit closes the job cleanly in one shot.

FAQ

How is the 42/52mm 36x45 kit different from the 42/52mm 45x45 kit?

The bearing diameters are identical, but the contact angle is different. The 36x45 version is for integrated headsets with an angled lower cup, while the 45x45 is for traditional external headsets. The contact angle must match your headset design exactly.

How do I know which kit applies to my frame?

Check the headset model number against the Cane Creek bearing compatibility chart, or remove your current bearings and measure both the outer diameter and confirm the cup geometry. If unsure, reach out to Dialed Cycling Lab and we can help you identify the correct spec.

What happens if I install the wrong contact angle bearing?

Incorrect contact angle causes improper load distribution between the bearing and cup races. This leads to rapid wear, reduced bearing life, and potential damage to the cup seat surface in your headset or frame. Always confirm the angle before ordering.
