Terrible product/worse customer service


This mount dropped my bike, caused hundreds of dollars worth of damage due to a defective ratcheting wheel, and Thule customer service neglected to compensate for the damage caused by the mount


Boise, ID


Works great, but lots of wind noise


I've had a pair of Side Arms for approximately 8 years in constant use. After this much use, I can still drive like a lunatic and not worry about the bikes on the roof. Awesome. The older of my two SideArms doesn't really fit a 29" mountain bike wheel, but the slightly newer one does. Apparently they increased the length of the arm around 7 years ago. Wide tires fit, up to about 2.8", but that's pushing it. What I would like to see improved: Air drag. These racks make a lot of drag, in my Subaru, it eats around 1-2 mpg with no bike in them. They are also noisy. The rear wheel strap always wants to be in the way while loading a bike. I tuck it under the aluminum v rail, but it can sometimes be tricky. A nice refinement would be something that easily holds that strap out of the way while loading a bike.

The Enginerd





I have had a pair of these bike mounts for 5 years. Installation instructions were clear. They have been on my car since the install. I use them with mountain bikes with the wonderfully wet and muddy Pacific Northwest. I have had zero problem. I have taken road trips to Moab several times battling high winds and they have worked flawlessly. My riding buddy has had the same mounts also with zero problems. I would happily recommend them.
