Step-by-Step Guide: How to Replace a Spoke on a Mountain Bike
To replace a spoke on a mountain bike, first remove the wheel from the bike. Flip the wheel over and use a spoke wrench to loosen the spoke nipple at the base of the hub and remove the broken spoke. Thread a new spoke into the hub and guide it through the proper holes in the rim, crossing over and under other spokes to create the proper tension. Use the spoke wrench to tighten the spoke nipple until the wheel spins true. Reinstall the wheel on the bike and enjoy your ride.
