Wolf Tooth Performance Headset

ZS44 refers to a Zero Stack headset with a 44mm head tube inner diameter, while 28.6 indicates it is designed for a standard 1 1/8-inch steerer tube. This is a common specification for many mountain and road bikes, but you should always measure your head tube or check your bike's manual to ensure compatibility.

The Black Oxide coating provides an extra layer of protection against corrosion, which is particularly useful if you ride in wet or muddy conditions. While they still offer the high load capacity of chromium steel, this treatment helps extend the life of the bearing by resisting rust better than untreated steel.

Yes, this headset is compatible with carbon frames that use a 44mm press-fit head tube. However, because you are pressing metal cups into a carbon frame, it is critical to use the correct installation tools and follow your frame manufacturer's specific torque and grease recommendations to avoid damaging the carbon.

Yes, Wolf Tooth designs their headsets to be serviceable. If the bearings eventually wear out, you can purchase replacement cartridge bearings without needing to replace the entire headset assembly.

Yes, you will need a headset press to install the cup into your frame. While some home mechanics use DIY methods, a proper headset press ensures the cup is seated perfectly straight, which is essential for smooth steering and preventing damage to your frame.
