I had a can of Wurth dry lube a couple of years ago - no fling on the rear wheel because there was bugger all on the chain, it wore out during the use of that can so never again. > I've managed to find some PJ1 blue label lube, brilliant stuff; spray the chain after a ride (as described, but it doesn't penetrate the O-rings) leave overnight and it won't need doing again for ages. Very little rear wheel cleaning needed too. Top stuff , recommended 8-)
