I use this just as a temp stand to hold bikes while I lube chains, pump tires, and get them set up for the day's ride. Works for our singles and (carefully) for our tandem. Would be nice if it had a little more lateral stability, but on the plus side it fits all bike tires from race, to commuter, to mtn bike widths. It's really handy.
Ive used this rack many times now and find it easy to operate. It has a very snug fit and leaves me feeling comfortable that my bike is safe. It also has a very clean finish that looks sharp. This is the best rack that Ive ever owned and Ive had several.
I've owned a number of racks over the years and this is by far the easiest to use, the least stressful on the bikes, and the most flexible with respect to frame style, wheel size, etc. I was easily able to fit a fat bike and full suspension MTB bike together.
The rack also has a cool built-in bike repair stand which has come in useful on more than one occasion.
The only problem I've had with it was when my wife ran the car through the car wash the day before we were leaving for a cycling trip and the temperature overnight was well below freezing. I had to get out a hair dryer to warm up the front wheel clamps so they would extend.
