Has anyone else tried this stuff? Rock 'N Roll is the best lube I've used yet. It's a degreaser and a luber, so you put the stuff on and wipe it off, then the lube stays where it needs to be. The only thing I do differently is I put it on the chain in the middle of the cassette and the front rings. Since it's a degreaser, it could degrease something it shouldn't when applying it over the cassette. They have a website, too: Rock 'N Roll Anyone else tried this stuff?
