So, I'm gonna have to keep my bike outside a fair amount, nothing long term, just overnight and during the day while at work. I would like to have a cover especially for overnight. I have seen that there are MANY options out there in all price ranges. I'm wondering if anyone has any input for me on what works best(products/practices etc..) My biggest concerns are rain and direct sun. I've heard it's not good to cover the bike while its still hot, and that it needs to breathe. A waterproof cover might cause rust? Any thoughts, recommendations? Thanks as always to the coolest bike forum out there!
