We invented the modern headset in 1992 with the Aheadset and the 110 series is a continuation of that legacy of precision, craftsmanship and performance.
We know the 110 headsets are the best in the world, and we want to make sure that they have the best guarantee in the world.
The Hellbender bearings are built to live in the most extreme conditions, keeping you riding smoothly through rain, mud, grit or whatever the road and trail throws at you. Using Stainless Steel bearings and advanced sealing elements.
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
The 110-Series offers the widest array of configurations available in a premium headset. With over 26 straight and tapered combinations, whatever your headset requirement, we have a premium solution for you, backed by our lifetime guarantee and superior customer service.
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.

This bike uses a proprietary lower headset bearing (37mm ID, 49mm OD) that we do not produce. I would recommend contacting your local Specialized dealer to aid in finding you headset replacements.
So long as you use our crown race and bearing cover (which come witha complete Cane Creek headset) there should be no issue. The bearing dimensions should be the same, however I would recommend buying a handful of IS headset shims in case there is a small difference in the height of the upper bearing. I cannot find the exact Acros dimensions listed online. IS shims can be purchased on our website, searchable by part number .HSS2050 and .HSS2051 - Get a few of each, they are always helpful to have in your toolbox for future use even if not needed on this bike.
We do not make a 110 headset that fits this particular bike. It represents a much less commonly used size. We do have replacement bearings however, that can be swapped in using the existing compression ring and headset bearing cover. The two bearings you would need are BAA1160 and AAA2083. You will have to call your order in, as AAA2083 is a highly unique bearing and not listed by itself on the website.

Verified OwnerCustomer service wanted to warranty my 110 Series Headset with a Series 40 replacement. That’s not a “lifetime warranty” when you are swapped a lesser quality than what you originally purchased. I won’t buy ANY Cane Creek products again knowing this.
