If your tired of a bouncy rack you are always watching the mirror for, then this is for you. Solid as a rock over any terrain. With the extension it holds four bike very well and the fact it converts down to just two is great for smaller groups. Folds super flat to hang on the wall in the garage. Could not be more pleased. One downside, it's a bit heavy but you don't get solid without some decent steel in there. Highly recommend!
