I live in a mild climate, weigh less than 140lbs, and use White Lightning regularly on my chains. Possibly because I do alot of hill work, I often reach Sheldon's elongation limit in about 3500 km. I find that my cogs and chainrings outlast several chains, however, possibly because I reserve the small cogs for high-speed cruising.
