The GeoShift Performance Angle Headset allows you to adjust the geometry of your bike by changing the head tube angle, available in 1 or 2 degree options. This unique design lets the bearings sit at an angle to align with the steerer tube, preventing creaking noises commonly found with angle headsets that feature a spherical design. Reduce the head tube angle to make for slacker geometry and added stability on fast descents, or increase the angle using the opposite orientation of the headset, to make for steeper geometry and quicker steering with maximum front wheel traction.
- Enduro black oxide coated chromium steel bearing included on both the upper and lower
- 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)
- Machined in the USA with lightweight, strong, durable aircraft-grade 6061 aluminum
- Includes: Upper and lower cups, bearings, crown race, star nut, shims, stem cap with 5mm integrated spacer and bolt
- 1 Degree Adjustment
- Long version is designed for headtube lengths between 115 - 140 mm

Wolf Tooth headsets are machined here in our Minnesota shop with aircraft-grade 6061-T6 aluminum. They are designed to be lightweight, strong, and durable. Our headsets have three levels of industry-leading custom sealing to protect bearings from the elements and prolong the life of the headset. This has a stack height of 3mm and is available in a variety of colors to match other Wolf Tooth anodized color options. These IS headsets are made exclusively for Specialized frames with molded-in internal bearing cups. Like all Wolf Tooth Premium Headsets with Enduro stainless steel bearings, the Premium IS Headset for Specialized has a lifetime warranty.
Compatibility
- Any Specialized bike that uses an IS (Integrated Standard) headset with 42mm upper bearing diameter.
- Uppers and lowers sold separately.
- Enduro stainless steel sealed bearings included on both the upper and lower.
- 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).
- Some bikes, like the Stumpjumper EVO, have an adjustable headset that resembles a ZS headset where an upper cup is pressed into the frame. Our bearing will fit into that cup and our top cap will fit neatly on top.
Measuring to determine compatibility with your Specialized frame
1. Disassemble the headset, remove upper bearing from the frame
2. Use the depth blade on a caliper to measure from the top of the headtube to the corner where the 45 degree taper starts.
