I've got a couple of these in the garage and they are great, super easy to mount and remove bikes without the stress of hanging them somewhere. If you're a super weight weenie and your rig is lighter than 12lbs the spring might be a little strong tend to push the bike out of the mount.
This is a great rack and you can connect them together if you have more than one bike. They are really stable and super easy to load your bike - just wheel it onto the stand and it is held. Just pull it off to ride. No lifting or latching required. Also this rack does not touch the bike frame just the tire tread. I even use it to hold the bike for cleaning and chain maintenance. Can be folded flat when not in use and even taken to the races for easy bike storage outside your car. I plan to buy more for my other bikes.
I use a few of these in my garage to hold the bikes i use regularly. It's easy and fast getting bikes in and out of the stands and, because these stands hold the bikes vertically (no leaning that would cause the front wheel to turn), the stands allow me to store the bikes closer together, saving space.
Works great and I connected it to the other one to hold up two new road bikes with disc brakes that I belatedly found out that I cant hang on the wall from front rim hooks because hanging can introduce air into the hydraulic fluid. Grrrrr.
