EC49 HEADSET EXTENDER LOWER - EXTERNAL CUP

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 headsets are machined here in our Minnesota shop with aircraft-grade 6061 aluminum. They are designed to be lightweight, strong, and durable. Premium Headsets with Enduro stainless steel bearings have a lifetime warranty.

Our headsets have three levels of industry-leading custom sealing to protect bearings from the elements and prolong the life of the headset. These EC headsets are for frames with external bearing cups, which places the bearing outside of the frame.
