They have on each side of the tooth bottom, a groove which evacuates sand and mud from the sprocket, this way dirt does not accumulate between sprocket and chain. This accumulated dirt causes over tension to the chain as a result sprocket and chain wear out very quickly, and may even block your bike. With this mud grooved sprocket you avoid these problems.
