If this seems to be the issue. Have you ever thought of beefing up this spot with a drop of solder or possibly JB Weld to give it a little added strength? Don't know if it's possible but I always like to try something to improve longevity.the cable has no adjustment, no relearn required when changing out for a new one. Only when cable gets stretched will you need to do this. We have not had to re learn one yet, like plowboy said you can clean them without relearning. Believe me having a cable on hand has made some happy people on the trail, went from frowning to smiling again in a 20 minute fix.
