“Most of the Sunday team has been riding guard sprockets for a long time, so it was just a matter of time before we did our own. 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. It’s available in 25 and 28 tooth sizes and 4 colors: Black, Blue, Raw and Red. Find it at your local Sunday Dealer here.“- Sunday Bikes
