The big knob ( fnarr fnarr) is a garmin locking nut thingy me missus got me..think it was twelve quid off the bay, it's a big lump but works brilliantly to stop someone nicking the cradle when your bikes outside some village B and B in the south of France all night...you do it up, lock it and the knob just spins instead of catching. Good idea
