Internal Shimano Dura-Ace FC-R9200 or FC-R9200-P 36t Chainring.

The Shimano Dura-Ace FC-R9200 inner chainring is designed for the FC-R9200 and FC-R9200-P 2x12-speed cranksets. With a 110 mm bolt circle, this chainring ensures quick and smooth shifting, ideal for demanding cyclists.

The outer chainrings feature Hollowglide technology, which, thanks to its hollow construction, offers weight reduction without compromising stiffness, improving power transmission and front shifting precision.

Features:

• Material:
  • Outer: Anodized aluminum, carbon fiber reinforced plastic (CFRP)
  • Inner: Anodized aluminum
• Technologies:
  • Hollowglide: Extremely rigid hollow structure that reduces weight while maintaining high strength. Improves power transmission and makes front shifting faster and more precise.

Note: The letter combinations (NK, NH, NJ) behind the tooth numbers must match for the large and small chainrings. The Dura-Ace FC-R9200 chainrings have been specifically coordinated to provide superior shifting performance in the combinations intended by Shimano.
The chainring is new, original, and is sold without the original packaging.
