Gritty chain lube???

I guess I could have asked, but....well, it seemed like a stupid question.

I've learned the most important stuff through asking the stupidest questions. Never hesitate to ask, even if the LBS dude does look at you as if you're from Mars. I usually preface my stupid questions with, "OK, this is the dumbest question you'll probably get all day, but I'm gonna ask it anyway..."
