How to Replace Shift and Brake Cables

Bike maintenance

Cable replacement restores crisp shifting and braking. Frayed or corroded cables cause poor performance and can snap unexpectedly.

Quick Answer: Replace cables annually or when shifting/braking degrades. Cut housing square, use cable cutters, lubricate before installation, and adjust tension after cable stretch settles.

When to Replace Cables

Inspect cables for fraying, rust, or kinks. Sticky shifting despite derailleur adjustment indicates cable friction. Brake cables showing any fraying need immediate replacement for safety.

Installation Steps

Remove old cables and housing. Cut new housing to match old lengths using sharp cable cutters. Thread new cable through shifters and housing, then attach to derailleur or brake caliper. Pull cable taut and secure anchor bolt.
