Have these holders aware bought not for a bike rack but for 2 MTBs whose total weight should be (with accessories such as lock etc) held. This makes the wall holder with flying colors, is stable and well-made, but he is good limited (4 stars) for this purpose, but that is not the manufacturer's fault: 2 MTBs with sweeping croissants handlebars are simply too wide. Even if the handlebar alternates (one right, one left) and cranks folded intricately into each other, depends the front (more distant from the wall) bike just now as on the front brackets where they run up. The whole holding but.
