Query: These stands work great!

I've tried several types of storage options for my rather large collection of bicycles and I have to say that these stands are by far the best solution for me. They are stable and hold nearly all of my bikes upright without putting undue stress on their wheels. I'm storing everything from old beater mountain bikes to my nicest skinney tire racing bikes and everything in between without a worry. The stands are very stable and I haven't had any problems yet.
