Avian Carbon Headset

Avian make three types of headsets. Integrated Step-down, Standard Integrated, and Tapered Integrated.  These headsets feature an 8mm thick carbon top cap. The standard and tapered headsets come with an expanding fork plug, which can be used with carbon forks in place of a stem lock or star nut.  All of the headsets come with split bearing races for easy slip on installation.

Expander Plug Disclaimer: The Expander Plug included with our 1-1/8" Standard & Tapered headsets is intended for use with 1-1/8" fork steerer tubes with a 23.2 Inner Diameter. That means if your fork has a steerer tube thicker than 2.7mm, our expander plug won't fit inside it. Fork manufacturers that use thicker steerer tubes than 2.7mm should require a stem lock design, or some other type of internal locking included with their fork.
