Shimano SLX CN-M7100-12 Chain

Shimano SLX & 105 CN-M7100 12-Speed Chain

Keep your momentum moving forward, no matter how bumpy the path gets. The Shimano CN-M7100-12 is a highly durable 12-speed chain designed as a central component of the SLX M7100 mountain bike and 105 R7100 road/gravel families. Engineered to cascade the same trail-taming technologies found on flagship XT and XTR ranges, this chain offers a near-identical shifting experience under heavy pedal loads, but at a more budget-friendly price point.

The CN-M7100 features asymmetrical, highly specialised plate profiles. Its inner plates are designed with extended, chamfered edges that pair beautifully with Shimano’s Dynamic Chain Engagement+ chainrings and Hyperglide+ cassette tooth profiles. By firmly wrapping around the teeth, this proprietary design significantly reduces chain vibrations, runs exceptionally quiet, and virtually eliminates dropped chains on rough terrain. Complete with a premium SIL-TEC surface treatment on the roller link plates, this chain shrugs off grit and moisture to keep your shifting crisp ride after ride.

Key Technologies

• Hyperglide+ Optimised: High-precision moulded contact surfaces allow the chain to guide smoothly and quickly in both directions across the cassette. Keep power on the pedals and shift smoothly even under heavy climbing torque.

• Extended Inner Plates: Promotes a tighter, more secure lock with the chainrings, ensuring stable chain retention on technical singletracks and gravel descents.

• SIL-TEC Coating on Rollers: An advanced fluorine plating process applied to the roller link plates reduces mechanical friction, sheds mud easily, and extends overall chain life.

• E-Bike Compatible: Built with solid pins and high-tensile steel to effortlessly withstand the extra torque of mid-drive E-bike motors.

Pros & Cons

• Incredible value that brings high-end Hyperglide+ shifting performance down to a highly accessible price point

• SIL-TEC low-friction coating dramatically cuts down on drivetrain noise and limits wear in gritty trail conditions

• Extended inner plate design provides top-tier chain retention, keeping you secure on bumpy terrain without needing a chain guide

• Fully E-bike certified to handle high-power electric motors without stretching prematurely

• Included SM-CN910-12 Quick-Link makes initial assembly and installation simple

• Strictly directional design; installing the chain with the Shimano logo facing the frame will severely degrade shifting performance

• Does not use hollow pins or SIL-TEC coatings on the outer plates (unlike XT/XTR), making it slightly heavier than its premium siblings

• Quick-Link is non-reusable and must be replaced with a fresh link if you ever disconnect the chain for cleaning
