I travel a lot up and down motorways, 500miles a week, and I'm not always in the same car so getting a bike rack specific to a make and model wasn't for me. It was a toss up between the seasucker which a friend uses and this, and this treefrog is litterly exactly the same as the seasucker except you can fit bigger axel bikes as well as the standard road bike. This is 100% secure there's no way even in strong winds and rain it's coming off....I've tried it and while doing motorway speeds, just remember your car height before you go through a drive through. Theres no marks left on the car that a quick wipe with a pad doesn't get rid of and there's no scratches left either. The only reason for 4 stars is i wish it came with a different retaining pin, not a biggy though because I just use my usual front wheel pin and tighten it on that way, and to be fair if you have a normal road bike the one that comes with it'll fit fine anyway. Litterly takes 4 minutes to set up and get the bike on and drive off.
