The roof bars are very easy to use and make a high-quality and safe impression. Before I ordered these from Amazon a test with borrowed carriers was once popular. After having worked smoothly was the purchase perfect. In my Audi A3 Sportback (Bj 06/2013) with original trusses of Audi (groove track) fit the Thule ProRide591 perfect. The support for the driver's side must be converted unfortunately when both carrier and bicycles are to be mounted in the direction of travel. But is only a work of 10 minutes and an allen key (not supplied) is necessary. To Veranschauung I uploaded here a photo showing the carrier after the conversion. Who it does not matter in which direction are the bikes which can dispense with the conversion. Whether in aerodynamics plays a major role, I dare to doubt. Who ordered the set has the advantage that the same key can be used for both carriers. Whether the Schösser then but actually deter theft is questionable. Thieves of opportunity but it will definitely scare. Strong buy recommendation for this item!
Addendum: As already described by other customer enters drive with the carriers (without bicycles) from a speed of 50 km / h light singing on the. However, these wind noises are not very strong and are "swallowed" from 100 km / h above the other driving noises. During the reconstruction of the support for the driver's side of the carrier is offset about 8 cm forward, which obviously interferes with other buyers of ProRide 591. Visually might that be a shortage, but technically that's my opinion, an advantage. In this way, the handlebar of transportable bikes do not come together. Here, too, I place a photo available.
