The durable e*thirteen Helix R chainring was CNC machined from high quality aluminum and is available in the colors of the Helix cassettes. The Narrow-Wide Design of the 4th generation improves the hold and reduces the noise of the chain during pedaling. Thanks to the E13 Flip Flop design and the Direct Mount type, it is quickly and easily installed on compatible cranks with the same interface. In addition, the chainring can be turned around, which allows 2 different chain lines or Offsets to be ridden.
