Riding with my wife yesterday, her front shifter cable housing failed dramatically--the cable pulled out of a 4" section of housing. The low limit screw on the FD was long enough to keep her in the middle chain ring, where she does 99% of her riding, so we finished the ride fine. We just happened to have a strong tailwind and she shifted into the big ring for the first time in years. Gonna replace all the cables and housings today.
