The Shimano Dura-Ace CN-M9100 chain is a 12-speed chain designed for both the XTR M9100 and Dura-Ace R9200 12-speed groupsets, featuring an extended inner plate for improved chain retention and a SIL-TEC surface treatment for enhanced durability and smooth running. It offers better chain engagement and holding on sprockets, leading to smoother shifting and reduced vibrations. The chain uses a quick-link assembly for easy, tool-free installation and comes with hollow-formed pins for weight savings. 

Key Features

• Extended Inner Plate: The enlarged portion of the inner plate creates a strong connection with the chainring teeth, which helps prevent the chain from falling off and improves overall chain retention.

SIL-TEC Surface Treatment:

• An advanced plating process with embedded fluorine particles results in smoother, low-wear running and extends the chain's durability, especially in various conditions.

Enhanced Shifting:

• The computer-designed plate profiles work seamlessly with Shimano's Dynamic Chain Engagement+ (DCE) chainrings and cassette sprockets for faster and smoother shifts, even under heavy load.

Quick-Link Assembly:

• Allows for quick, tool-free assembly and disassembly of the chain, making maintenance easier.

Hollow Pin Design:

• The pins are hollowed out to save weight without compromising strength.

Durability:

• The combination of SIL-TEC coating and a chromizing treatment on the pins and rollers ensures long-lasting performance.

Directional Chain:

• The chain is directional, meaning it needs to be installed in the correct orientation.

Compatibility:

• Designed for the Shimano 12-speed XTR M9100 and Dura-Ace R9200 groupsets.
