Cane Creek’s 40-Series sets the standard for performance, durability and value. Drawing from the premium 110-Series design, the 40-Series includes all the features necessary for a durable, lightweight, long-lasting headset.
We make it easier, by developing consistent graphics, interchangeable parts and over 40 configurations to meet almost every size need. Sold in straight and tapered assemblies or tops & bottoms, tops are available in either short (9mm) or tall (15mm) stack height bearing covers. Precision engineered by Cane Creek in Fletcher, NC.
Featuring a full alloy construction – sealed cartridge bearings, 6000 series alloy cups and materials, and a sealed steel crown race, the Forty series headset sets the standard for all other headsets to be judged.
The ZN40 bearings are corrosion-resistant zinc-coated, machined steel cartridge bearings with hardened steel balls, which vastly increases the longevity of the 40 series headsets.
Our patented Interlok spacer design provides solid interface between the top cover and spacer stack, meaning they “nest” together and into the top of the bearing cover, which helps minimize shifting under load while riding; and shave 25% in weight off a standard alloy spacer stack. Spacers sold separately
In 1992, we brought the Aheadset®, the original threadless headset, to market – kicking off a major change in the way bicycle frames and forks would be developed going forward.
The original design of that revolutionary headset is still found in almost all bikes on the market today.

Depends on the model year but for 2022/23 you need part #.
We do not have a rebuild or direct replacement option for the AD4 shock.
While information is available on most modern bikes, I do not see the headset specification listed on Kona's website for the 2006 Kona Dawg Deluxe. We suggest reaching out to Kona directly or obtaining the necessary SHIS measurements using the guide here: https://canecreek.com/everything-you-need-to-know-about-headsets/

Verified OwnerLike all Cane Creek components, a great fit & a quality component.

Verified OwnerWorking great, only point of improvement would be to explicitly say in the product listing that the lower comes with a crown race. (Which may be obvious to everyone who’s ever ordered a headset part before, but I’m a first timer)
