It is an OK bike tie down, but if you use one, I would suggest, at least for the first time or two, you have someone with you when loading the bike.
Steep ramps, no beaver-tail and there is a really good chance you will get hung up at the ramp-garage transition with something like this hanging under the bike.
My bike will bottom out if the trailer is high enough to cause a steeper then normal ramp angle.
And this past fall I did get the bike stuck when unloading at Cape May.
And I still would not trust the clamp alone, I would have at least have two straps on the sides. There is tremendous lateral pressure on the bike when making turns.
