Rain does not hurt bikes. Just be sure to have the chain lubed, and also that there are drain holes in the frame if you have internal cable routing.I have done many cross country trips with bikes (including full suspension MTBs) on the outside of the car for over a month at a time. Every imaginable weather condition other than salted roads. Never had a problem.
