Wolf Tooth EC34 Premium Upper Headset
Wolf Tooth Premium headsets are machined out of aircraft grade aluminum and feature high-end bearings made by Enduro. They are engineered to use the largest possible ball size and are filled with high-pressure waterproof lubricant. A pair of dual-lip seals ride in micro-grooves to keep out water and debris.
Stainless Steel Bearings provide unparalleled corrosion resistance
Highly recommended if your headset will be exposed to wet conditions or sweat
