I use this type of support for several years and am fully satisfied. Positives: - Bicycle can be very quick to set up and place it on the car roof. When set to the particular bicycle is activated, it takes 15-30s maximum. - So far, I did not have a bike guy who could not fix. - Support is given in instructions with a bicycle weighing up to 17 kg - Bike is very stable fixed by the holding principle (symmetric frame mount). - Carrier can be fastened flexibly to the crossbars. - Due to its slim design, several (at least 5) carrier can be attached. - Carrier is equipped with a lock as an accessory can buy and share identical locks, so that you need only one key. - Good value for money - Tip: If you use several bike rack, it is advisable for it to use a separate cross beam system. I have a car with roof rails and let the 4 bike rack always fixed completely on the cross beam system. As a cross-carrier system, I use a simple universal system that goes in width on the roof rails. Thus, the bicycle carrier can attach well to the outside. Besides, I need the 4 carrier not always individually fitted and removed, for example, when I'm driving in winter with roof box, which is therefore mounted on a second crossmember system.
