How to Replace Rear Gear Cable on a Mountain Bike: A Step-by-Step Guide
To replace the rear gear cable on a mountain bike, start by shifting the bike to the smallest gear using the shifter. Loosen the bolt holding the cable in place on the rear derailleur, and take out the old cable. Thread the new cable through the cable guide and attach it to the derailleur using the bolt. Pull the cable taut and tighten the bolt. Next, thread the cable through the shifters and cut off any extra length. Finally, adjust the tension using the barrel adjuster until the shifter and derailleur are in alignment.
