AFAM Self-cleaning front sprockets (+ in the reference) are available for MX and Off-Road use. On each side of the tooth bottom, they have 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 and 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.
