FC-09 Chainring

The Shimano Dura-Ace FC-R9100 11-speed chainrings provide premier shifting precision for road, gravel, and cyclocross drivetrains. These 52T rings are engineered to restore factory-level performance and power transfer to your 4-arm 110mm BCD crankset.

• Hollowglide Technology: The hollow outer ring design maximizes rigidity while minimizing weight. This prevents flex under high loads, ensuring crisp, reliable front shifting during sprints or steep climbs.

• Enhanced Efficiency: Developed specifically for HG 11-speed chains, the optimized tooth profile improves chain contact and efficiency, resulting in smoother power delivery and increased component longevity.
