How to fit road bike brake cables and sheaths?

Cables in poor condition can quickly lead to malfunctions in the transmission or braking system. If you're a regular rider, it's advisable to change your cables and sheaths at least once a season. Here's a tutorial to help you do just that.

• Time : 30 min
• Level : Easy
• Tools : Allen wrench set | Phillips screwdriver | Cable cutter | Pliers

Steps

Whether Campagnolo or Shimano/Sram, the steps are virtually identical.

1. Set the brake lever to the rest position.
   
   
2. Release the brake cable with the Allen key, then remove the sheath.
   Probikeshop tip: Locate the routing of cables and sheaths before removing them, so that you can reassemble the new elements in the same way.
   
   
3. Remove the cable from the lever.
   Probikeshop tip: Depending on the make and model of your levers, the cable is routed differently. Please refer to your levers' manuals.
   
   
4. Cut the new cable sheath to size, using the old one as a template.
   
   
5. Place the new cable in the lever.
   
   
6. Thread the sheath over the cable while fitting it to the bike. Don't forget to thread the end caps.
   Probikeshop tip: If the sheaths are not pre-lubricated, you can put a few drops of oil on the cables before inserting them into the sheath to reduce friction.
   
   
7. Finally, place the cable on the brake with sufficient tension.

Once you've installed your new cable, all that's left to do is follow the brake adjustment tutorial.
