Shimano CN-6600 Dura-Ace Ultegra Chain - HG | 10-speed - 116 Links
The Shimano CN-6600-10 is a super narrow Hyperglide chain for 3x10-speed road bike shifting systems. While perforated carrier plates reduce weight, an improved press-fit construction provides a more stable shifting performance. Chrome-plated pins increase wear resistance and a durable surface coating protects against corrosion.
