THE ABSOLUTE BEST.
110-Series
Cane Creek’s engineers were tasked with developing a no-compromise, best-in-class premium headset. With the introduction of our 110-Series, they did just that — choosing optimal materials, engineering the most effective internals and designing the best aesthetics available in a headset.

The 110-Series offers the widest array of configurations available in a premium headset. With the flexibility to purchase complete assemblies or separate Tops and Bottoms, tops are available in either short (9mm) or tall (15mm) stack height bearing covers, the 110-Series offers a premium solution for nearly all straight and tapered configurations on the market today. From Integrated (IS) Tops to External Cup (EC) Conversion Bottoms and everything in between, you can mix and match your headset purchase to best meet your needs.

Cane Creek ensures that whatever your headset requirement, we have a premium solution for you, backed by our NEW 110 Series 100% Lifetime Guarantee
