Like every other component on your bike, your shifter cables will eventually wear out. And when they do, you’ll know it: Corroded and frayed shifter cables are more likely to get stuck in the housing or catch on parts of your bike, leaving you with wonky shifting.
Don’t let an old cable get in the way of a smooth ride. Instead, follow the easy steps in our video for shifter cable replacement.

Steps for Shifter Cable Replacement
Shift the chain onto the smallest front and rear cogs.
Unwrap your bar tape in order to access the shifters.
Clip off the end cap and remove the cable from the old housing.
Fully remove the old cable from the shifter.
Use the old housing as a guide measure, and cut the new lengths of cable housing.
Use a pick to widen the new housing opening, and install the new ferrules. Use either plastic or metal ferrules—both will work.
Install the new cable into the shifter and through the new cable housing.
Thread the cable through the derailleur, insert housing, and tighten the bolt.
Snip off any extra cable, attach a new end cap, and crimp it to secure it.
