My dry lube (I prefer Rock N Roll) which by all accounts is gone after 1 ride in heavy rain. So I hit it with silicone to help prevent rust but not to really lubricate since its not that good at that.

Where I live, in rains probably 2-3 days then stops for 6-8.... so I can run a more "complex" routine. But again, it takes me all of 2 min. I also ride different bikes in the rain or not.

I spend 10 min each week prepping the bike I want to ride that week, rain or shine. I like my bikes and want to keep them as nice as I can for something that gets used daily, if not weekly. I also run Chris King hubs and XTR brakes on my rain bike, so I am maybe more sensitive to them getting too trashed than if they were cheapo parts.
