Main tube too long for Jeep Grand Cherokee


The rack installed just fine on the factory cross bars of my 2014 Jeep Grand Cherokee. I also have a Thule 535 thru axle rack on the same cross bars. When I opened the power tailgate after installation of the Thule Circuit the tailgate hit the back of the main tube and closed. Upon looking at it closer, the main tube of the Circuit was about 3 inches longer than any other Thule roof bike rack I have used on this vehicle. I had to return it.

I love it


I don't use a bike rack a ton but this one works great. Good looking, easy to use, and not too noisy. I did have the end cap come off and lose the real wheel carrier but it's an inexpensive replacement part.




Love it


Fits great on our Subaru factory crossbars and holds our mountain bikes safely. Left on top of the car while we stayed overnight on a road trip and slept good knowing they were locked down. Researched our fork sizes and didn't need the adapters. Happy with our purchase!
