The GeoShift Performance Angle Headset features a design in which the bearings sit at an angle that aligns with the steerer tube. This compares to angle headsets that have bearings that sit flat, which adds unneeded friction and stress on the bearings. The design with angled bearings also prevents the creaking that is common with angle headsets that feature a spherical design.

Wolf Tooth headsets are machined in the USA with lightweight, strong, durable aircraft-grade 6061 aluminum. Our Performance Headset is built to include an Enduro black oxide coated chromium steel bearing, a one-year warranty, and three levels of superior custom sealing to protect bearings from the elements and prolong the life of the headset.


  • Upper headsets ship with a star nut which can only be used on forks with steel or aluminum steerer tubes. For forks with carbon steerer tubes you will need a compression plug (sold separately; never use a star nut on a carbon steerer tube)
  • Consult measurement guide determine which headset will fit your bike.
