Replacing a Bicycle Derailleur Cable. Replacing a bicycle's cable is done the same way on almost all bicycle derailleurs and shifters. 1. Loosen the cable anchor bolt - the bolt that clamps the inner wire at the bicycle derailleur body. 2. Pull the cable inner wire out of the derailleur and cable casing.
