Thanks for the info on those "wax" lubes. I'll keep my eye out for them. I neglected to say I do clean my drivetrain, and recently did it quite thoroughly. It was so sweet in fact I considered not riding in this weather cuz I knew how our local sand and other grit gets into everything. But this is going to be my first full 5 day week commuting by bike, if it kills me, or my chain.
