The durable e*thirteen Helix R chainring is CNC machined from high quality aluminum and available in Helix cassette colors. The 4th generation Narrow-Wide design improves grip and reduces chain noise while pedaling. Thanks to the E13 flip-flop design and the Direct Mount type, it is quick and easy to install on compatible cranks with the same interface. In addition, the chainring can be reversed, allowing you to run 2 different chain lines or offsets.
