The AER Upper Headset Assembly is the premium offering of Cane Creeks headset line. Meticulously machined from aluminum and brilliantly anodized each part is its own little work of art. Featuring their hybrid bearing, two steel races contained within an aluminum cup. That offers a 35% weight savings without sacrificing durability, the AER Series-II headset is one of the worlds lightest. Fully compatible with Cane Creeks 40 and 110 series headsets, spare parts are readily available at most shops or direct from Cane Creek making service and replacement a simple task. For the lightest headset that doesn't sacrifice durability and longevity in the race for weight savings the AER Series-II is the ideal choice. Pair with a few of Cane Creeks AER Headset Spacers for a complete ultralight setup.

Compatible with almost every modern frame, there is a tall and short option for Integrated (IS), and Semi Integrated (ZS) headsets. If you have any questions about these headsets please contact us or check out Cane Creeks S.H.I.S. guide to determine the proper headset for your application.
