Adjust the geometry of your bike by changing the head tube angle. The GeoShift Performance Angle Headset 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 that increases turn responsiveness.

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 with have bearings that sit flat, which adds unneeded friction and stress on the bearings. Their 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. Their 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.
These are sold as upper/lower pairs. They have ZS44/EC44, ZS44/EC49, and ZS44/ZS56 sets, each with options for 90-115mm or 115-140mm head tubes. Like all Wolf Tooth headsets, the GeoShift Performance Angle Headset is made with lightweight, durable, strong aircraft-grade 6061 aluminum and has a triple-sealed system that protects bearings from the elements.
