+1 for dirty, dusty, dry conditions

There essentially are two types of chain lubes: dry and wet, rather Wax based or oil based. Oil based lubes will stick to the chain through sleet, puddles, splashes, mud and snow. However they also attract grime, grit and chain and ring and cog killing filth. Theoretically a wet oil lube lasts much longer than a dry wax lube. However, the chain gets so dirty and is such an attractant to grime and grit (the opposite of a clean well lubes chain) it's effectiveness on the drivetrain becomes deleterious. With an oil based or wet lube you need to constantly clean the chain of the gunk, grit and grime that will wear the chain and eat rings/cogs. However, wax dry lubes don't last nearly as long as wet oil lubes. In fact for very long rides 100k + is about the reapply interval. The chain will stay clean but the wax dry lube just doesn't last in ideal conditions. It's worthless in the wet/rain/snow/muck. The oil wet lube will last long past the point where it's collected so much grit/grime it's starting to eat the drivetrain.

The real question is what conditions do you ride in? Also whether you like reapplying dry wax lube constantly or completely cleaning and relubing your chain almost as often.
