Query: Not for more than one bike

Have used this model for about six months now, the retaining straps on the top bars slide to the end during longer trips. If you put two bikes on the rack the top bar can bite into the trunk top if you have a sedan and leave a dent. Not meant for heavier bikes or long trips. I have upgraded to the stronger Saris Bones 2 model. Now I can carry two bikes and have no more problems with bikes shifting or loose straps.
