What is the best chain lube?
The best mountain bike chain lube is the one that you use on a consistent basis and the one you apply after you have a dry/clean chain, and preferably the lube you apply the night before. It is helpful if you get a lube that is conducive to your conditions you ride as well. With that said, the 2009 MTBR winners are Chain-L Lube and ProGold Prolink.
