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.
This bike rack is great. Tired of kids leaving their bike lying all around the campsite. Bought this gem and it give them a place to put them and nobody is tripping over bikes. Assembled easy and looks durable.
