The Shimano FC-9000 52T chainring is a Dura-Ace replacement outer chainring designed for 52-36 double setups, delivering the precise chain engagement and crisp front shifting that race cyclists demand.

  • 52T outer chainring for FC-9000 Dura-Ace cranksets in 52-36 double configuration
  • MB type designation — matches the correct pin and ramp specification for the 52-36 pairing
  • Precision-machined alloy construction for race-level weight and stiffness
  • Shimano's SIL-TEC coating on select teeth for smooth, consistent chain engagement
  • Designed for use with Shimano 11-speed Dura-Ace and compatible road chains

Dura-Ace chainrings are precision items — the shift ramps, pins, and tooth profiling are engineered specifically for each chainring size and pairing combination. The FC-9000 52T (MB) uses the correct ramp geometry for 52-36 doubles, ensuring that front shifts remain fast and positive whether shifting up or down under load. Replacing a worn chainring with the genuine Shimano part maintains the shifting performance of a new groupset.

Designed for use with Shimano FC-9000 Dura-Ace cranksets in 52-36 double configuration. Compatible with Shimano 11-speed road chains (CN-HG900 and similar). Ensure the MB type designation matches your existing crankset pairing before ordering. Not compatible with FC-9100 or 12-speed cranksets.
