Wolf Tooth Premium Extender Lower EC Headset Black EC49/40 10mm

Wolf Tooth headsets are machined in the USA with aircraft-grade 6061 aluminum.

The Performance Headset is built to include a black oxide coated chromium steel bearing. Headsets stand above the rest with three levels of superior custom sealing to protect bearings from the elements and prolong the life of the headset. They are designed to be lightweight, strong, and durable. These EC headsets are for frames with external bearing cups, which places the bearing outside of the frame with these headsets.

Compatibility

• Any frame that uses an external cup headset with a 34mm upper head tube inner diameter and 34mm, 44mm, or 49mm lower head tube inner diameter.
• Enduro black oxide sealed bearings included on both the upper and lower.

Recommendations

The Wolf Tooth crown race installation adapter will help avoid damaging the crown race seals.
