The Sunday Knox sprocket is made of 6mm thick 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 1/8" chains and many 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 crank slide. This sprocket has a 23.8mm bore and includes an adapter for 19mm and 22mm spindles.
