How to Adjust Gears on a Mountain Bike: A Step-by-Step Guide
To adjust gears on a mountain bike, start by shifting to the highest gear and loosening the cable tension. Then, shift to the lowest gear and tighten the cable tension until the chain is aligned with the gear. Make sure the chain is running smoothly through all gears while pedaling and adjust the barrel adjuster if necessary. Test the gears on different terrain and make further adjustments as needed.
