So during my ride yesterday I fell over on the side of the street. Nothing major, just a small scratch on the knee and the handle bar. The pannier took most of the hit, but the left shifter was smacked as well. It still works fine, but it's no longer tight at all with the bars. It feels like it's the cable it self that holds it in place and I can rotate it about 30 degrees each side.
Does that mean its interior attachment broke?
