EXTREME is for mountain bikes: mountain bike needs something that can take lots of dust, and/or muddy slop being kicked up on the chain from the front wheel. 

ABSOLUTE DRY is for the road bikes: Road bikes generally tend to pick up more dirt and dust from static discharge, so a thicker, dryer membrane is needed. 

GOLD is for both mountain and road bikes. A universal dry lube suitable dry dust and protection from slightly wet conditions. 

HOLY COW is a very settled wet lube that is as clean or cleaner than most dry lubes. Dirt and grit can be quickly wiped from the chain unlike a dry line. 

Holy Cow is the latest in the Rock N' Roll Lubrication's line up of chain lubes. For all you riders that like to ride with a wet lube but could live better without all the dirt and grit of a wet lube, Holy Cow is just for you.

It performs fantastically, like the other Rock N' Roll chain lubes. Being a little bit of a wet style chain lube, what little dirt or grit that does get on the chain, can be wiped away quickly and easily as it cleans and lubes in one step. Keeps chain looking brand-new, "out of the box" clean. Good for all conditions.
