How to Stop Chain Slap on Your Mountain Bike: Tips and Tricks
To stop chain slap on a mountain bike, you can adjust the rear derailleur or add a chainstay protector. To adjust the derailleur, increase the tension on the chain by turning the barrel adjuster clockwise. A chainstay protector can be added to absorb the excess movement of the chain. Additionally, make sure your chain is properly lubricated and replace it if it is stretched.
