To replace your shifter cable, first ensure that the shifter is in the highest gear
(otherwise you wonít be able to remove the cable), next loosen the gear assembly
so that you can rotate it around the handlebars a little;
this is to allow easier access to the hole where the cable exits the shifter.
To access the hole, you will need to use a Philips screwdriver to remove the cover indicated below.

Once the cover has been removed, simply push the cable through a little
until you have enough showing that you can grip it where it exits the other side of the shifter
and then pull through the remaining cable.
