💡 Why Replace Your Crank Sprocket?
Over time, sprocket teeth can wear or become damaged, causing poor chain engagement, slipping, increased drivetrain noise, and inefficient power transfer known as "chain stretch". Replacing the crank sprocket assembly restores smooth pedaling, improves riding efficiency, and helps extend the life of your chain and drivetrain components.
