Macneil have dug into their classics and re-released their original guard sprocket from back in the day! This CNC machined 6061 aluminum, one piece guard and sprocket combo is 6mm thick with 1/8″ teeth, 3 crank arm mounting holes and a 22mm center (19mm adaptor included). The guard sprocket will come in 25 and 28 tooth versions with black for the only color and a weight of 4.79 oz. for the weight. I remember I ran one of these in a 36-hole version when they first came out years back when Ruben Alcantara still rode for them, haha.
