I know. Yet it is...I guess theoretically, the only thing that could go wrong is if your peg breaks off. But believe me, once its locked down, it is pretty rigid, because it basically clamps it down from both sides. the only other things I do is tie up the front wheel, because that could swing, but a bungee does that easily.
Plus its easier on the forks because there is no load on them, all the load is on the frame.
Funny, when I've gone riding, I've gotten as many or more looks of admiration for the rack than my bike :coocoo:
But check out their website, they've gotten some pretty impressive review posted there.
