Wolf Tooth WT-1 Chain Lube is a synthetic lubricant and a chain treatment in the same bottle. As a synthetic chain lubricant WT-1 will improve the mechanical efficiency of your drivetrain while lasting 3-5x longer than most other chain lubes. As a chain treatment WT-1 will clean your chain by pushing dirt and debris to the surface where it can be wiped away. It will also protect your chain in all riding conditions and allow you to ride longer between applications.
