Hi guys I need help naming a part of my old bicycle. Its part of the V brake and its the thing that the spring tension centering screw screws into. This is the same part that the spring is attatched to. Ive looked everywhere to no avail. The reason I am asking is because the thread where the screw screws into has snapped so it is difficult to set up the brakes properly. Is it worth simply replacing this part or shall I just buy a new set of V brakes?
