Yeah most lubes collect dirt. I have tried a ton of them. DuPont Chainsaver is what I have used for a long time now. Does not attract dirt after it dries and the Teflon in it makes the chain about silent. The tiny HP gain is nice but the giant savings in rotational mass is WAY worth it if you like the twisties or track. Very apparent when flicking the bike around. I need some nice light weight wheels too!
