didnt know if i should post this here or not, but since its a mtb i guess i will. I have a 2 - 2.5 hr drive today in rain and want to put the bike on the rack ontop of the car. Is it safe for the bike to be subjected to the rain like that for a few hours time? what do most of you folks do when you have to bring your bike somewhere and its pouring out? Should i make sure its completely dry afterwards? towel it down?
