Ass Saver Ornot

If you don't have a dedicated rain bike with full fenders, you need one of these. Super featherweight (19 grams) and installs in seconds. It's not going to keep you totally dry, but will do what the name says, save your ass. These work on bikes with tire widths up to 35mm. Especially useful for seats with cutouts to help avoid that unwanted instant bidet action once the road gets wet. You could stay inside when it rains, Ornot.
