Wolf Tooth WT-G Precision Bike Grease is a waterproof, synthetic oil-based lubricant for cycling-specific applications. It reduces friction on moving components while protecting them from contaminants, water, and corrosion. WT-G also prevents non-moving components from seizing together due to corrosion or galling. This is a grease that can be used on bottom brackets, hubs, headsets, general bicycle assembly, and more.
