How to Fix Your Gears on a Mountain Bike: A Comprehensive Guide
To fix your gears on a mountain bike, start by shifting the bike into the lowest gear. Then, adjust the cable tension on the derailleur until the chain smoothly moves up to the highest gear and down to the lowest gear with ease. If you notice any skipping or slipping of gears, adjust the barrel adjuster on the derailleur until the shifting is smooth. Finally, check the limit screws on the derailleur to make sure the chain does not fall off or get stuck between gears.
