Quality And Value
Our 40-Series headset is the entry point for performance, quality, and value. Drawing from the premium 110-Series design, the 40-Series includes all the features necessary for a durable, lightweight, and easy to use headset.
Highlights:
We make headsets easier. Our headsets use interchangeable parts and over forty configurations to meet almost every size need. Sold in straight and tapered assemblies or tops & bottoms, tops are generally available in either short (9mm) or tall (15mm) bearing covers to further customize the look of your cockpit setup.

*Our ZN40 bearings (used in all 40 Series headsets) can feel rough in hand initially. This is a necessary side effect of the corrosion-resistant zinc coating used on the balls and races. This initial roughness wears in, becoming smoother with use, and extends the overall lifespan of the bearings.
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.

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)
