The Knox sprocket is made of 7075 aluminum and comes with a full guard on 1 side of the sprocket. Even more important is the fact that it's designed to fit larger chains like half-link chains. It's made super strong and will help you protect your chain from being hit when slipping off a rail or messing up on a crankslide.
