I bought these to put inside a storage shed with my bikes to hold them up- didn't need it because the bikes held each other up. However, it is really nice and I may anchor it to the concrete in my carport for a place to park them while we are using them.
Really easy to put together, and it holds my mountain bikes without hitting my disc brakes. I did have to alternate the mountain bikes front to back to make them fit better, but the road bikes have plenty of room.
