e*thirteen Helix Race e*spec

The Helix Race e*spec is specifically designed for the Fazua Ride 60 system. It uses a direct-mount interface, so please verify that your current crankset utilizes this specific mounting standard before purchasing.

Yes, this chainring is fully compatible with both 11-speed and 12-speed drivetrain systems. It features an updated narrow-wide tooth profile designed to retain the chain securely across both configurations.

The 53mm chainline is optimized to accommodate modern e-bike frame spacing and boost standards. This alignment allows you to run smaller chainring sizes effectively, which can help maximize the usable gear range of your cassette.

The integrated alloy dust cover acts as a barrier against trail debris, grit, and mud. By keeping contaminants out of the motor interface and drivetrain components, it helps reduce premature wear and maintenance intervals.

The updated M3 narrow-wide tooth profile is engineered to reduce chain noise and improve retention. By creating a more precise interface between the chain and the ring, it minimizes friction and helps the drivetrain run quieter and smoother under load.
