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

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.

What if I used a 110 bearing in a 40 series cup with the 40 series cover? Are all the bearings compatible? Tate asked on September 21, 2023

All bearings are compatible with all headsets as long as the same size bearings are used. You cannot use different top bearing covers and cups as these are specific to each series.

What 110 headset would fit my CruzBike S40. Looking to replace the Cane Creek Viscoset headset Chuck, Gary asked on September 5, 2023

Your Cruz S40 uses the EC34 Viscoset. The ViscoSet is a top headset design so you only need to replace the top headset. Our 110 Series part number: BAA0165K

Hi Cane creek, will these fit BMC Roadmachine 2022 model? Looking to replace the headset bearings which are FSA MR155 and MR019. Measurements are: Top 41.8 X 6.5, 45/45 Bottom 51.8 X 7.5, 36/45 Thank you Samuel.S asked on August 24, 2023

Yes our bearings should work but you may require some IS shim spacers for the upper headset since our bearing heights are not exactly the same.

The lower does not seem to be very durable/robust. The last 2 have virtually disintegrated while installed in my frame, within months. The issue is, that my Lynskey Cooper CX is designed for this headset, although I think I've found an equivalent from Ceramic Speed.

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.
