How to Repair Mountain Bike Gears: A Comprehensive Guide
To repair mountain bike gears, first, diagnose the issue. Check if the gears are not shifting smoothly or if they are skipping gears. Then, check the derailleur hanger for damage, lubricate the cables, and adjust the barrel adjuster. If necessary, remove and clean the cassette and the chain. Ensure the derailleur is properly aligned and tensioned. Test the gears to make sure they shift smoothly.
