The durable e*thirteen Helix R chainring is CNC machined from high quality aluminum and available in different colors. The Narrow-Wide Design of the 4th generation prevents the chain from jumping off and reduces the noise while pedaling. Thanks to the 3-bolt design Direct Mount type, it is quickly and easily installed on compatible cranks with the same interface.
