Courtesy of innovative Narrow Wide® technology, our ACID Chainring not only keeps your chain securely on the sprockets but also runs more quietly than conventional chains. Its alternating narrow and wide tooth profile improves chain guiding to prevent annoying chain drops, while the direct mount design directly transfers all of your power from the crank to the chainring for maximum forward motion. With their modern, dynamic design cues, our ACID chainrings are an eye-catching addition to any bike.
