What Makes the ZN40 41/52mm Kit the Smart Headset Fix?

The Cane Creek ZN40 Series 41/52mm Bearing Kit packages both headset bearings in one order, covering the complete upper and lower replacement for integrated headsets using a 36x45 contact angle. These zinc-coated cartridge bearings feature hardened steel balls and precision-machined races designed to resist corrosion and deliver smooth steering performance through demanding mileage and wet-weather conditions. Replacing both bearings at once as a matched pair eliminates wear imbalance and returns your headset to full factory performance in a single service.

The 41mm upper and 52mm lower configuration targets specific integrated headset designs within the Cane Creek 110-, 40-, and 10-Series headset lineup, making it an accurate, purpose-built replacement rather than a generic part. If your headset has logged serious mileage and both bearings are due, this kit is the efficient, cost-effective answer compared to sourcing each piece individually. For riders who do their own wrenching and want the job done right the first time, this is the kit to grab.

FAQ

What is the difference between the 41/52mm and 42/52mm bearing kits?

The upper bearing size is different. The 41mm upper fits certain integrated headset cup geometries, while the 42mm fits others. This is a real dimension difference, not a rounding variation. Measure your existing upper bearing before choosing between the two kits.

Does the 36x45 contact angle apply to both bearings in the kit?

Yes. Both the 41mm upper and 52mm lower bearings in this kit use the 36x45 contact angle, which is the correct specification for integrated headsets designed around this geometry.

Is it better to buy the kit or purchase bearings individually?

The kit is the better choice when both bearings are worn or have similar mileage. It ensures matched components, simplifies ordering, and typically offers better value than sourcing each bearing separately.
