Anodised aluminium construction: Protects the teeth against wear while keeping weight low, extending service life and maintaining crisp shifting over time. 4-arm, 80 mm BCD design: Ensures a secure fit with FC-RX610 cranksets for optimal stiffness, keeping the chainring stable under force and maintaining reliable performance. Matched pairing with the 46T-NS outer ring: Ensures correct spacing and shifting alignment across the full double chainring setup, delivering consistent front shifting and preserving drivetrain accuracy. This chainring is perfect for riders who want consistent control and reliable power transfer during long gravel sessions. Its durable construction and targeted tooth design keep the drivetrain stable under pressure, while the 30T size offers practical gearing for off-road gradients. Each feature works together to maintain performance even as conditions become more demanding.
