The video you mentioned, which features the Yakima HighRoller is dishonest.
Dishonest in that the HighRoller snap around rack mounts were LOOSE and not properly tightened, and thus yielded the results shown in the video.
See the video at the 1:45 to 1:49 mark for confirmation of the improperly installed bike rack
(Note the loosely/improperly installed snap around mounts rotating around the cross bar).
Proper installation of the Yakima HighRoller results in zero play, under load, at the rack and bar mount locations.
Yakima's best roof bike carrier, the HighRoller, features a wide super strong wheel tray, with wide mounting points, and a maximum bike weight limit of 50 pounds.
The Yakima HighRoller's wide and strong wheel tray, coupled with the double hoop arms and wheel grips anchor the bike and provide a very secure manner of transporting a bicycle.
The video in question:
BIKE Magazine TechTest Thule/Yakima. on Vimeo
Note: It should be noted that at the end of the video, BIKE Magazine claims that the HighRoller mounting hardware loosened up during testing.
Again, this is dishonest as it was more likely their initial failure to install, inspect, and ensure a proper installation.
Had the HighRoller been properly installed, the mounting hardware would not have loosened up so quickly and easily, if at all. (Personal experience has shown zero loosening of the HighRoller mounting hardware over the past year+ with regular uses at California freeway speeds of 70 mph)
While BIKE Magazine decided to publish this video test in it's final, as seen form, BIKE Magazine callously used footage of the improperly installed Yakima HighRoller rack.
It is fair to assume that most who viewed the video may not have noticed that the HighRoller rack was installed improperly, and would have made a bike rack comparison decision based on the published dishonest video test.
In the end, BIKE Magazine does make note that the swaying action viewed in the video was significantly reduced after tightening the mounting hardware, but fails to provide accurate video footage in the final video for the view to consider.
