Product Details

The Wolf Tooth GeoShift Performance Angle Headset (2° version) is the ultimate solution for riders seeking aggressive geometry customization. With a ±2° head angle adjustment, it provides dramatic changes in steering feel—slacken your front end for added stability on steep descents, or steepen it to sharpen handling and improve climbing precision.

Unlike spherical angle headsets that can creak or shift under load, the GeoShift uses a slanted bearing interface that perfectly aligns with the steerer tube, ensuring tight, creak-free performance. It's CNC-machined in the USA from 6061 aircraft-grade aluminum for top-tier durability and accuracy, and comes loaded with Enduro black oxide-coated bearings for smooth performance in any conditions.

Designed for frames with a ZS44/ZS56 headset configuration, this complete kit includes everything needed for installation. A star nut is included for alloy or steel steerers; carbon steerer users will need a compression plug.

  • ±2° Head Angle Adjustment – Enables aggressive geometry tuning for either stability or quick handling
