I utilize Yakima Q-bars on a luxury car with Malone saddles for my Hobie Kayak. I recently purchased a Specialized Roubaix carbon fiber bike and I needed a way to transport it in a secure manner. Up to the point of the bike purchase I liked the idea of being able to install or remove the bars from my car in just a few seconds and I wanted to keep it that way. After careful research I was able to determine that the Boa's were the only solution in keeping my current configuration intact and it works great. I am now looking to install a second unobtrusive Boa for my wife's bike. I will then be able to have a Kayak and two bikes on the car completely secure with the Yakima locks and if I wish I can go back to the luxury mode in just a matter of a minute or two with no tools or hassle.
