Road and MTB chain Shimano Dura Ace XTR CN-M9100 12v 126 maillons Quick Link - ICNM9100126Q

A high-end 12-speed Shimano chain for road and mountain biking

The Shimano CN-M9100 is a high-end 12-speed chain developed for Shimano XTR and Dura-Ace drivetrains. Part number ICNM9100126Q refers to a version of 126 maillons, supplied with a Quick Link to facilitate fitting and maintenance of the drivetrain.

Designed to complement modern 12-speed Shimano drivetrains, this chain combines precise gear changes, low friction, quiet operation and excellent durability. In particular, it features SIL-TEC technology, which helps to reduce friction and improve the smoothness of the drivetrain.

With its 126 maillons length, it is suitable for a wide range of set-ups, including those using wide-range MTB cassettes or 12-speed road drivetrains. However, the length must be adjusted to fit the bike before fitting.

A chain developed for Shimano 12-speed drivetrains

The CN-M9100 has been designed to complement the Shimano 12-speed drivetrains. Its directional design optimises performance with HYPERGLIDE+ technology, particularly when shifting under load.

On mountain bikes, this technology enables particularly fast and smooth gear changes, even when the rider continues to apply significant pressure to the pedals.

The chain is also designed to work effectively with compatible Shimano 12-speed cassettes, helping to maintain precise engagement between the sprocket teeth and the chain links.

SIL-TEC technology: smoothness and reduced friction

Shimano SIL-TEC treatment is used on the CN-M9100 to reduce friction between the chain’s various components.

In particular, this technology helps to:

• improve smoothness of operation
• reduce drivetrain noise
• minimise friction-related losses
• promote greater durability
• facilitate transmission operation in difficult conditions.

To fully benefit from these properties, regular cleaning and lubrication remain essential.

126 maillons: a length to suit your needs

The ICNM9100126Q version is available in 126 maillons. This generous length is particularly useful for high-capacity drivetrains, notably certain 1x12 MTB set-ups.

Please note, however, th126 maillons does not mean the chain must be fitted in its entirety.

The final length must be determined based on:

• the chainstay length
• the number of teeth on the chainring
• the size of the cassette
• the 1x12 or 2x12 configuration
• the capacity of the rear derailleur

A chain that is too long or too short can disrupt the drivetrain’s operation and accelerate wear on certain components.

Quick Link: a more convenient fitting method

Part number ICNM9100126Q is supplied with a Quick Link Shimano compatible with this chain.

The Quick Link allows the chain to be closed without using a conventional connecting rivet. This is particularly convenient when replacing the chain or carrying out maintenance.

The Quick Link Shimano is designed for single-use only. Once removed, it is recommended that you replace it with a new quick link rather than reusing the old one.

Road, MTB and 12-speed drivetrains

The CN-M9100 is particularly suited to the Shimano XTR 12-speed MTB, but it also forms part of the high-end Shimano 12-speed ecosystem.

It is particularly well-suited to drivetrains using:

• Shimano XTR 12-speed
• Shimano Compatible Dura-Ace 12-speed
• certain compatible Shimano XT/SLX 12-speed configurations, depending on the components used

Compatibility must be checked against the complete drivetrain, including the cassette, crankset and derailleur.
