Hooks do not hold the wheels properly and the bikes tend to lean to one side making it difficult to arrange them where the don't interfere with each other. Also the hook brackets are loose fitting on the support rod and will slide around if the wheel touches them when you are trying to hang the bikes which causes spacing problems. This was a more expensive rack verses some other wall mount options and I was very disappointed in the products performance.
BUY THE CHEAPER OPTIONS....you will be better off.
