I use Break Free CLP on all my bikes chain / drivetrain components and have for years. Road, MTB, Hybrid, Tandem and SS. I know its not specific to bikes, but I always have plenty on hand it has kept my handguns and AR's running like tops and has worked as good as anything I have ever tried on my bikes. Granted I subscribe to the thought that keeping a clean drive train is the best way get the maximum life out of it so, I clean the chain and cassette on a regular basis.
