How to Replace Gear Cable on Mountain Bike: A Step-by-Step Guide
To replace the gear cable on a mountain bike, first shift the gears to the smallest cog and loosen the cable bolt on the derailleur. Pull the old cable out of the shifter and remove the housing. Cut a new cable to size and thread it through the shifter, housing and derailleur. Secure the cable to the derailleur using the cable bolt and adjust the tension using the barrel adjuster. Test the shifting before cutting the excess cable and crimping the end.
