Rock N Roll Extreme lube
I like it since it is very smooth, and doesn't get the chain very dirty either. It is also the easiest to clean off when you need to clean the bike, but stays on when water is around. I don't promise any miracles with this stuff, it is just easy to work with. When applied it is a wet lube, but then it dries into smooth film.
The great thing is this lube is degreaser and lube at the same time. So the applicant being the degreaser, not only degreases the old lube away, but then dires and leaves the new lube there alone.
In my opinion, no lube out there will work, if a person doesn't look after it. Any lube will atract particles, and get the chain dirty. That is why you have to keep an eye on your parts, and clean them more frequently then you would think.
Lastly this lube saves me mucho money on degreasers, since it already has one in it!
To clean, I take my chain off (power link), put some lube over it and let it all run down when holding the chain vertically. After that I just take a garden hose with a gun attached to it and blast the chain with the water. This takes everything off and makes the chain clean enough to put on my bed. Then after that I just wipe off my chainrings, and the grime comes off w/o once again using anything special. Takes me about 15-20 minutes.
So in conclusion, that is why I like this lube.
