Shimano Dura-Ace 7900 39t 130mm 10spd B 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.
