I use this for my drivetrain. I also cover my seat with two or three plastic shopping bags and then secure the bags with a copious amount of cheap electrical tape, around the saddle itself, not just around the seat post. This is to keep the bag from ripping in the wind. If you do remove the saddle, fine. If you remove the saddle
and seat post, remember to plug/cover the hole that is left so water doesn't accumulate inside of your frame. Have a good trip.
