Maybe you're too fastidious in your method of chain lubing. I just turn the cranks a few revolutions while giving a light stream of (Teflon) chain lube and then wipe the chain off with a rag. We've all probably got slight variations in our method, and like Scrod, I'm not a fan of wax lube either. I remember reading an article by a race mechanic who said he would lube chains then give them a very light coating of grease to keep the lube in place and give better shifting performance. I've been meaning to test that claim.

Wait... are you turning your cranks clockwise when you lube your chain? You should try turning them counterclockwise since you are in the southern hemisphere. Coriolis effect, dude.
