Wolf Tooth 1 Degree GeoShift Performance Angle Headset

Wolf Tooth 1 Degree GeoShift Performance Angle Headset Info

Wolf Tooth 1 Degree GeoShift Performance Angle Headset is a precision tool for riders who want to fine-tune their bike’s handling without changing frames or forks. By adjusting the head tube angle by a full degree, the GeoShift lets you tailor stability and steering feel to your terrain, riding style, or race goals.

Installed in one orientation, the GeoShift delivers a -1º change for a slacker front end, increasing confidence and stability on fast descents. Flip the headset orientation and you get a +1º adjustment, sharpening steering response and improving front wheel traction on tight, technical terrain. It’s a simple, reversible way to dramatically alter ride character.

Unlike traditional angle headsets that rely on flat or spherical bearing interfaces, the GeoShift is engineered with bearings that sit at an angle aligned with the steerer tube. This design minimizes friction, reduces bearing stress, and eliminates the creaking often associated with angle-adjust headsets. The result is smoother steering, longer bearing life, and quiet performance under load.

Machined in the USA from lightweight yet durable 6061 aluminum, the GeoShift Performance Angle Headset uses Enduro black oxide–coated chromium steel bearings and Wolf Tooth’s triple-seal system to protect against water, dirt, and trail grit. It’s a performance-focused solution built for real-world riding, not just garage geometry experiments.
