Great Add On
This is a great add on to the Yakima Hold Up 2. When you fold it up with all 4 trays on it, it is pretty tall..but I have a pretty tall car, so it doesn't matter. Also having all 4 trays on makes the beast pretty heavy. It is awkward and heavy to carry, so I keep it attached most of the time. This also makes folding the rack up somewhat difficult to do by yourself. Regardless though, this is the best rack for carrying 4 bikes, because it keeps your bikes from hitting each other. it keeps your bikes from falling on the ground, and it keeps your bikes from bouncing around.
