Our bumpers don't detach... We use a reversible system. We can flip from red and blue by moving our reversible flap that has red on one side and blue on the other. We flip them up and down but I know some other teams go left to right. It only takes us about 30 second to flip four (4) corner bumpers (last years) and about 45 seconds to do two (2) full side coverage bumpers (2 years ago). If you want to see what the look like message me and I will get you a picture. Hope this helped!!!
