I know there are other posts regarding chocks but I wanted to add this and maybe save someone from the frustrations that I’ve had. Various friends recommended various chocks but they DO NOT work with the fat front RM tire and I know because I tried them. I’ve had to find two other guys to help get my bike out of the chock when I get where I’m going. But the Wheeldock is made for the RM tire and none of this rocking back and forth till my shoulders and back are outta place. It’s a great USA made product and good service.
