has an accommodating arse
I’d be a lot more hesitant on a chrome ball that’s bolted on and could itself rotate.Henny Penny I don't know much about ball mounted racks but be stuffed if I would be hanging many $$$$$$$ of bike off something that is designed to facilitate pivoting movement. Even with some form of chastity belt to wedge the thing in place. At least look at taking the ball off and using the hole in the tongue.
On a European style goose neck towbar where the “ball” can’t turn and isn’t shiny plated I’ve had zero cause for concern with my German clampy thing.
Have had both bikes on it and even driving like a tool on twisty roads it’s not moving.
