These are an earlier iteration of the 1Up bike racks so they were only designed with round/square bars in mind. That being said, they do have a slot on the bottom for the mounting hardware that may be able to utilize T-Bolt hardware for slotted crossbars if you are able to find appropriate parts at a local hardware store or rack-shop; but we have yet to test that fully ourselves so we cannot guarantee anything at this time. This would make it a, "do-at-your-own-risk," sort of install if you wanted to attempt it.
