What is the difference between the regular and the Lite?
Lite means it is environmentally friendly i.e. "light" on its impact on the environment.
Technically there is a difference between the Lite and Original Dumonde lubes, they differ only in their concentration. “Lite is less concentrated for easier application and optimum performance.” The light is for road biking and the regular for mountain biking and touring. I noticed a slight difference in the drag in the drive train between the two so if you are road racing use the "lite" project.
The lite is also a dry lube. You will have to apply it more often, but it will keep your chain cleaner in the long run.
