Rock n' Roll - the original pink stuff. Great lube because it is nice and thin so it flows where you need it to, but also sets up nicely overnight and lasts well. It is also a cleaner (the cleaner solvent is what makes it thin and penetrating), but I've found not to use it as directed which calls for it to be applied in a stream over the casette -- this results in the solvents penetrating the hub and breaking down the grease in the hub.
