The New GeoShift Performance Angle Headset from Wolf Tooth allows riders to alter the geometry of their bike by changing the head tube angle by 1º. These are sold as an upper/lower pair, with ZS44/EC44, ZS44/EC49, and ZS44/ZS56 pairings and options for 90-115mm or 115-140mm head tubes. 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: +1º and -1º. Position the angle headset with -1º facing forward and slack will be added to the geometry, which creates more stable steering for fast descents. Conversely, switching the orientation of the headset will add 1º 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.
