Adjust the geometry of your bike by changing the head tube angle by 1º with the GeoShift Performance Angle Headset. It allows you to change the head tube angle by -1º to make for a slacker geometry for added stability on fast descents, or by +1º by using the opposite orientation of the headset to make for a steeper geometry for quicker steering with maximum front-wheel traction.

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 to 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 6061 aluminium. 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.

Compatibility:

• Upper headsets ship with a star nut which can only be used on forks with steel or aluminium 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 a measurement guide to determine which headset will fit your bike.

Upper assembly features:

• Ultralight Stem Cap With Integrated Spacer plus an aluminium bolt and a star nut
• 5mm top cover = 6mm total stack
• O-ring seal prevents water intrusion around the steerer tube
• Custom-moulded upper lip seal provides additional protection for the upper bearing
• Optional shim washers if needed

Lower assembly features:

• Custom-moulded dual-lip seal on the crown race to protect the lower bearing in the toughest weather and trail conditions
• Service and additional parts available
