Shimano GRX RX810-1 Gravel Crankset – Precision-Engineered for Mixed Terrain

Built for Gravel Dominance
This Shimano GRX RX810-1 single-chainring crankset delivers race-ready performance for gravel adventurers and endurance cyclists. Featuring a 42-tooth asymmetric narrow/wide chainring optimized for gravel grip and reduced chain drop, paired with lightweight 175mm aluminum arms, it balances aggressive climbs with smooth descents on unpredictable surfaces.

Key Performance Features
✓ Shimano Asymmetric Chainring Design – 110 BCD platform with offset teeth geometry for superior chain engagement on loose gravel or technical climbs
✓ Hollowtech II Spindle – Durable yet featherlight construction (656g total) withstands long-distance rides
✓ 11-Speed Compatibility – Seamlessly integrates with Shimano GRX/Series 8000 drivetrains for precise shifting
✓ Pedal Ready – Includes 9/16″ pedal spindle standard for instant installation

Why This Crankset Stands Out
Compared to standard gravel cranksets:
🔥 15% lighter than SRAM Rival alternatives while maintaining torsional rigidity
🔥 25% fewer dropped chains vs non-narrow/wide designs in mixed terrain testing
🔥 Full Shimano GRX ecosystem compatibility – upgrade your complete drivetrain with confidence

Perfect for cyclists tackling ultra-endurance gravel events (e.g., Unbound Gravel) or daily commuters navigating urban-rural routes. The direct-mount design ensures easy installation without proprietary tools.
