Shimano Dura-Ace FC-7900 Inner Chainring

The Shimano 7900 inner ring receives completed nickel plated and blackened anodization, then has the outer most part of the ring machined and polished. This process adds strength and rigidity while matching the cosmetics of the 7900 components. It fits all standard 130mm bolt pattern cranksets, but is profiled to work specifically with 7900 outer chainrings.

  • 130mm bolt pattern
  • Anodized and polished
  • Profiled teeth
  • Made in Japan
