This is a very cool trailering device. Easy to install. I still use a wheel chock for the front wheel on my open trailer, just to keep the front tire straight.
Holds the bike well. Just be sure to line up the pegs perfectly even before stomping down to lock it in place. I had it too close to the rear brake lever on one trip and it scratched and grooved the brake lever from bouncing around. The bike wiggles just the slightest amount, but as long as you have the locking jaws centered over your footpegs, it works perfectly...and no more scratches. I was skeptical at first, so I did a slow, but bouncy test ride at slow speeds before taking off down the highway at 75 mph! I like it, and would buy it again.
