Not if you slip off Ease of crash damage? I've landed ON my disc before and not bent it. They're pretty sturdy things, most people use them these days, and a lot of people are now using them front and rear. If you're worried about hitting it while sidehopping, go the other way, or learn to sidehop properly. It's a common misconception that discs are easy to land on and bend, they're not at all from my experience.
