E*Thirteen Chainring Round Helix R Guidering Direct Mount 49g

The stylish Helix R chainring is CNC milled in one piece from 7075 aluminum and then anodized. This chainring not only looks stylish, it is also lightweight and is suitable for all 11-speed and 12-speed drives. This completes the setup of your bike. During the development of the chainring, the special G4 tooth profile was further developed and now prevents the chain from falling off even more reliably. At the same time, the revised tooth profile is intended to reduce wear on the drive system.
