Durability And Value

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.

Forty

Setting The Standard

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.

Cane Creek Zn40 headset bearings

ZN40 Bearings

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. 

Forty Series Headset

Interlok® Spacer Compatible

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

Cane Creek Headsets

A Legacy of Innovation

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.

Hi I've a 2006 kona dawg deluxe & I require a new cane creek headset with spacers, please advise. Thanks Ryan Ryan Ridley asked on April 12, 2023

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/

Working 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)

Name: Reed Mann
Position: Design Engineer
Year started: 2022
Best part of being a part of the Cane Creek family:  It’s very refreshing to work for a small, tight-knit company where we all share the same passions and to develop new products that make cycling better for everyone.
What you’ll find me doing on the weekends: Obviously riding bikes, but also wrenching on bikes or cars, exploring the mountains, and watching F1 races.
How I got here (at Cane Creek): Feeling pretty unfulfilled with a corporate engineering job, I happened to see that Cane Creek was hiring. I jumped at the opportunity to get my hands dirty working on the latest bike tech and was fortunate enough to be offered the position.
