Chain lube in either wet or dry formulations.

Choose the lube that meets your needs. Wet lubricant goes on wet and stays wet for maximum smoothness, quiet riding and superior rust protection.  Does better in wet extreme weather conditions. Dry lube sets up a dry 'wax-like' film that attracts less dirt & grime for off-road or dusty/dirty riding. Require more frequent re-application.

Either Can also be used on derailleurs, shifters, cables, and brake pivot points
