+/- 0.5 Degree Adjustable Headset Cup Alloy Frames

Our Feral +/- 0.5 degree headcup fits Specialized Bikes with Aluminum Frames that feature adjustable headset cups and allows you to steepen or slacken your headtube angle by 0.5 degrees instead of a full 1.0 degree using the adjustable headcup from Specialized. We also made a few minor design mods that provide better fit and performance.

CNC Manufactured from a single block of 1061-T6 Aluminum to ISO 2768 Fine Standards, our headcup is strong and precise. We then finish with 120 Micron Bead Blast, Anodize, and Laser Engrave the Feral MTB Components brand for a unique part that is both functional and attractive.
