These bars are super strong, Hercules strong, and relativity light weight. I have the 50 inch bars on my Toyota Yaris and they fit great. I have had them on my car for two years now and they have supported everything from mountain bikes to my friends being jackasses. Bottom line: If your looking for a super solid cross bars to hold all your outdoors gear or even an elephant or two look no further.
I would highly recommend this for any one who has a Thule roof rack. I had my roof rack for two years before i got the fairing and i don't know how i survived without it. It cuts down on noise, saves gas and was super easy to install. Furthermore, i'm pretty sure it almost manages to make my Toyota Yaris look fast. The only reason i didn't give it five stars is because it is a little expensive for what is essentially a large piece of plastic.
Phenomenal bike mount. I have used these to carry my bikes both on day adventures and on 1,200 mile drives between Colorado and Wisconsin. They fit my mountain bike, road bike and track bike just fine and keep them securely locked in. It is fairly easy and intuitive to use and install. Definitely buy the lock cylinders so you do not have to worry about your bikes getting stolen.
