This part connects the trailer to the coupling with a round tie rod. It is placed in the tie rod and secured in the coupling with a locking pin (Standard Forged Hitch & Steel Hitch) or with a bolt and nut (Classic Hitch). This flexible connection can easily stretch, allowing the user to put the bike down without disconnecting the trailer.Burley Item Number: 741147 EAN Code: 840840002976 Supplier Number: 950037
