So I am now jumped over my shadow and told me not mess big way. Since the Thule ProRide 591 was the best thing I could find on the net.
Delivery came after 3 days and I was thrilled when unpacking. This looks so incredibly stable. The assembly "from right to left" was simple - if there was some reviews some concerns. Installation on the Thule WingBar then takes less than 1 minute. Simply push it, festclippen, finished. I still have so much dragged to the thing - because nothing moves more. Bombenfest.
Without bike start from approx 90 km / h first whistling. But that is all in tolerable framework. Bicycle assembly easily (have a mountain bike and a city bike tried).
Approved for bikes up to 20kg and up to 130 km / h should be sufficient for most claims.
From me an absolute buy recommendation.
