Question about Thule FreeRide 532

Depending on the type of bars (rectangular or oval), there are two types of attachment. For the rectangular ones, there are attachments that attach to the bike rack. I, however, have 6.5 cm oval bars. For these bars, you have to insert hooks in the central channel of the bar (after removing the rubber protection) that are screwed into the clamps to lock the bike carrier. Ideally, look at the instructions (https://www.thule.com/-...)

Should fit, unfortunately I have sold the carrier again as I am now travelling with a rear system. So I can't measure it.
