The Subrosa Shred sprocket is built to do just that: Shred! This an inexpensive answer to a fully machined sprocket. Instead of machining a huge block of aluminum in a bunch of costly steps, the Shred Sprocket is stamped out of a 5mm thick 6061-t6 Aluminum plate, and then CNC’d smooth to clean up the look. This way you can cut back on price without sacrificing any strength. We also trust this sprocket to be used on our complete bike line.
