A cable break prevents you from shifting almost as much as a dead battery does for electronic shifters. (Only one cable breaks at a time, so some limited shifting is possible.) Yesterday, it was the cable to my front derailleur. Previously, the cable to the rear derailleur broke. This is far from a tragedy, of course, and I was able to complete my ride, albeit at reduced speed because I was stuck in my small chainring. It got me to thinking that it might be worthwhile to change the cables periodically before they break. Does anyone do this? I can manage a broken shifter cable every so often, but I was wondering if others replace the cables as preventive maintenance.
