e*thirteen Helix R Direct Mount Chainring | 11/12-Speed | Boost/SuperBoost - black

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 4th generation Narrow-Wide design improves grip and reduces chain noise during operation. The design of the chainring allows it to be mounted on both sides and thanks to the direct mount design it can be installed quickly and easily on compatible cranks with the same interface. In addition, the chainring can be reversed, allowing 2 different chainlines or offsets to be used.
