Avian make three types of headsets: Integrated Step-down, Standard Integrated, and Tapered Integrated.

The Step-down Integrated is generally for mini-expert sized bikes with a 1-1/8" head tube that uses a fork with a 1" steerer tube. 

The Standard Integrated is generally for pro sized frames that have a 1-1/8" head tube. 

The Tapered Integrated is for a lot of the newer, higher-end pro sized frames that utilize a head-tube design that has a 1-1/8" top bearing and a 1.5" lower bearing. 


  • 8mm & 18mm carbon fiber top cover options available
  • one 1-1/8" sealed bearing
  • one 1.5" sealed bearing
  • 72mm expander plug
  • one 1-1/8" lower bearing race
  • one 1.5" lower bearing race
  • Avian laser logo top cap & screw

The Standard & Tapered headsets are available in two top cover options, 8mm and 18mm. Some riders like a low front-end and others like higher front ends, this option helps you adjust without the use of tacky looking spacers. The Step-down just comes with the 8mm as it's intended for smaller riders who need their front ends as low as possible. All of our headsets come with split bearing races for easy slip on installation.
