The New GeoShift 2º Performance Angle Headset
from Wolf Tooth allows riders to alter the geometry of their bike by changing the head tube angle by +/- 2º. These are sold as upper/lower pairs, with EC44/EC44, EC44/EC49, and EC44/ZS56 pairings and options for 90-115mm or 115-140mm head tubes. The EC44 uppers are compatible with frames that require ZS44 uppers. This new headset was designed, engineered, and machined in Wolf Tooth’s Minnesota machine shop.
Two positions are marked on the GeoShift Performance Angle Headset: +2º and -2º. Position the angle headset with -2º facing forward and slack will be added to the geometry, which creates more stable steering for fast descents. Conversely, reversing the orientation of the headset will add +2º to the head tube angle and make for a steeper geometry and more responsive steering. Both angle options are indicated on the headset along with dashes that need to be aligned with the centerline of the bike. Full installation instructions can be found on the product webpage.
This new angle headset has a design that sets the bearings at an angle which matches the angle of the steerer tube. This design reduces the friction found in angle headsets that have the bearings that sit flat. This angled bearing positioning also limits the creaking found in angle headsets that have a spherical design.
The GeoShift 2º Performance Angle Headset builds on the existing GeoShift 1º Performance Angle Headset
. The 1º option is also sold as upper/lower pairs, with ZS44/ZS56, ZS44/EC49, and EC44/EC44 pairings designed for the same short and long head tube lengths. The EC44 upper will also work with frames that require a ZS44 upper. It is labeled EC44 instead of ZS44 because the relatively narrow 44mm head tube requires the bearing to live outside of the frame.
To accompany the new GeoShift 2º Angle Headset is a new Crown Race Adapter for 1 ⅛” steerer tubes to 1 ½” headset cups. All Wolf Tooth GeoShift Angle Headsets, and many Wolf Tooth non-angle headsets, use 1 ½” headset cups. This new Crown Race Adapter will allow forks with 1 ⅛” steerer tubes to use GeoShift Angle Headsets. Wolf Tooth also has a Crown Race Adapter for 1 ¼” steerer tubes to 1 ½” headset cups.

Installation of the Wolf Tooth GeoShift 2º Angle Headset is relatively simple, though the machined angle of the headset cups requires special care when being pressed into the frame. To help with this, two 3D-printed drifts that serve as installation guides are included in every purchase. A video detailing installation using these drifts is also available on the product page on the Wolf Tooth website, as well as a detailed compatibility guide to be sure that your bike can use a Wolf Tooth angle headset.

This is part of Wolf Tooth’s Performance Headset product line that was first launched in 2018. These are lightweight, strong, durable headsets made with aircraft-grade 6061 aluminum and have a triple-sealed system to protect the bearings from the elements. Performance Headsets use black oxide bearings made by Enduro. These bearings are engineered to use the largest possible ball size and are filled with high-pressure waterproof lubricant. A pair of dual-lip seals ride in micro-grooves to further protect the bearings from water and debris.
