Great for long distance or everyday use, particularly in the UK. Even on o-ring chains. The types I've used in the past operate from the carb vacuum. Obviously we all have our opinions about this, but after several years of boiling reynolds chains in Linklife along came the o-ring chain, with recommendations to keep it lightly oiled externally. I know that the oil gets flung off onto the back wheel, but so does all the grit.
