Shimano Dura Ace CN-7900 10 Speed Chain
The Shimano Dura Ace CN-7900 improves on Shimano's previous best the CN-7800 with a new asymmetric design for even better shifting.
- Asymmetric means that the inner plate and outer plates don't mirror one another.
- The outer plates are optimised to help prevent chain suck.
- The inner plates are optimised to mesh perfectly with the Shimano Dura Ace FC-7900/7950 chainset to deliver quieter and more efficient performance.
- This Super Narrow chain (5.88mm) is only suitable for transmissions with 10-speed cogs and 10-speed-compatible chainsets.
- Hollow pins and perforated plates help create a lighter weight chain.
- Approximate weight: 252g (114 links).
