The shifter cable and cable guide interfere with each other, causing long-term wear and tear on the cable guide. The original cable guide's shifter cable is positioned closer to the head tube, in front of the hydraulic hose, resulting in this issue. I have adjusted the position of the cable and hose and designed a new guide to resolve this problem.
