How to Change the Gear Cable on a Mountain Bike: A Step-by-Step Guide
To change the gear cable on a mountain bike, first shift to the smallest chainring and cog, then loosen the cable anchor bolt and remove the old cable. Thread the new cable through the shifter and cables stops, and pull taut before re-securing the cable anchor bolt. Adjust the indexing by shifting through the gears and fine-tuning the cable tension using the barrel adjuster until the gears shift smoothly. Finally, trim the excess cable and test the new cable by riding the bike.
