Wolf Tooth Headset Lower

This is an EC49/40 headset lower, meaning it is designed for frames with a 49mm internal diameter head tube and a 40mm crown race. You should verify your frame's headset standard or measure your head tube inner diameter before purchasing to ensure a proper fit.

Stainless steel bearings offer significantly better corrosion resistance, which is crucial if you frequently ride in wet, muddy, or salty conditions. They are less prone to rust and degradation over time, extending the lifespan of your headset.

The headset comes pre-packed with high-pressure waterproof lubricant and features dual-lip seals to keep contaminants out. While it is built for durability, it is still good practice to inspect and clean the seals periodically, especially after particularly muddy rides.

Wolf Tooth’s lifetime warranty covers defects in materials and workmanship. If the component fails due to a manufacturing issue, they will repair or replace it, giving you peace of mind that this is a long-term investment for your bike.

At 226.8 grams, this component prioritizes robust construction and longevity over ultralight weight. While it is built from aircraft-grade aluminum, the focus here is on durability in demanding conditions rather than shaving grams for racing.
