State two causes of accelerated wear on one side of the final sprocket teeth?

1. Misalignment of the chain: If the chain is not properly aligned with the final sprocket, it can cause increased friction and wear on one side of the sprocket teeth.

2. Uneven tension in the chain: If the tension in the chain is not evenly distributed, it can cause the chain to put more pressure on one side of the sprocket teeth, leading to accelerated wear on that side.

1. Misalignment between the final drive shaft and the wheel axle
2. Worn or damaged final drive chain
