Shimano FC-RX810-2 GRX 11-Speed Double Inner 31T-ND for 48-31T Chainring
- 80mm BCD, 4-arm layout
- Lightweight aluminium
- Compatible chain Shimano HG 11-speed
The Shimano FC-RX810-2 GRX 11-Speed Double Inner 31T-ND Chainring is a precise and durable replacement option designed to maintain smooth, accurate shifts in demanding gravel use. It provides a strong balance of low weight and stiffness for consistent performance, with the 48-31T pairing standing out for its efficient pedalling range and firm shift response under load.
Key Features and Benefits:
- Lightweight aluminium 31T inner ring with anodised teeth: This reduces mass while increasing wear resistance. This outcome supports long-term shift accuracy and consistent drivetrain performance in harsh gravel conditions.
- Stiff construction that forms a balanced 48-31T chainring set: This stiffness increases shift precision when the drivetrain is under strain. The outcome is stable engagement and reduced risk of hesitation during gear changes.
- 80mm BCD, 4-arm layout designed for FC-RX810 cranksets: This creates a secure interface with the crankset, improving power transfer through a direct, rigid fit. The outcome is more efficient load distribution across the drive system.
- Optimised compatibility with Shimano 11-speed HG chains: This pairing lowers friction and improves chain stability at varied cadences. The outcome is a smoother and more efficient transfer of power across mixed terrain.
- A matched 48T-ND and 31T-ND chainring design: This ensures correct spacing, ideal mesh, and reliable synchronisation between rings. The outcome is dependable front shifting and predictable gear progression throughout wide-range gravel setups.
This chainring supports riders who want stable power delivery and consistent front shifting across rough ground. Its light yet rigid build, paired with the matched 48-31T system, helps maintain efficiency when cadence varies and the drivetrain takes repeated impacts. Its compatibility with HG 11-speed chains strengthens both shift control and long-term reliability without adding unnecessary weight.
This 31T inner ring is built to restore full function to FC-RX810 2x cranksets with a dependable fit and clear performance gains. Its durable design and precise engineering make it a strong choice for keeping a gravel drivetrain running at a high standard.
