Wolf Tooth GeoShift 1d ZS44 - EC49 Short
Description
ZS44/28.6 UPPER - EC49/40 LOWER Headtube Length: SHORT 90 -114mm
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 on 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 aluminum. 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 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)

These lower headset cup extenders allow you to adjust the geometry of your bike frame by increasing the effective fork length by 10mm. They allow you to do things like use a rigid fork on a suspension-corrected frame or use a fork with a shorter axle-to-crown height rather than what the frame was designed to use. They can also be used to increase the bottom bracket height and lower the headtube angle.
Wolf Tooth Precision Headsets are machined in the USA out of aircraft-grade aluminum with superior sealing for protection against the elements. Available in a variety of colors to add some style to your bike. These EC headsets are for frames with external bearing cups.

The result is a headset system with incredible holding power and ease of adjustability.
