Everything is done with the installation of the bike racks and I am very pleased with the design and quality of your products. I installed them as per the instructions and our very eclectic assemblage of bicycles fit just perfectly. We are a very satisfied customer. I should also mention that all-in cost to build this was about $880, or $110/ bicycle. I think this is a good value as these will be in use as long as I am around….and likely much longer.
