Shimano Dura Ace CN-7801 10-Speed Chain.
The Dura Ace CN-7801 10-Speed Chain is zinc-alloy plated for easy gear changes and long life, and uses Shimano's connecting pin to eliminate weak links. Plates and rollers are optimized for smooth, accurate shifting. Use with 10 speed gearing only.
It is compatible with all SRAM and Shimano 10 speed drivetrains, and is in our experience less noisy than SRAM chains, despite being about the same weight.
