looks similar to the No-Mar mount/dismount bar that I use. And if so it is a snap to use as long as the wheel is held firmly. Takes about 10 seconds for each bead to dismount. Spray on some lube, put the nylon end between the wheel and the tire bead, pry up and swing it around. Mounting takes a little more but still once you get the knack it is about a 1 min to put the tire back on.
