Know before you buy
The CN-M8100 is specifically optimized for Shimano's 12-speed Hyperglide+ systems. While it may function with other drivetrains, you will achieve the best shifting performance and longevity by using it within a full Shimano XT or SLX 12-speed setup.
The included SM-CN910-12 Quick-Link is designed for easy installation, but it is a non-reusable link. You will need a pair of master link pliers to safely remove it if you need to take the chain off for maintenance.
SIL-TEC is a low-friction surface treatment that reduces wear and improves mud-shedding capabilities. This helps the chain run quieter and smoother for longer, especially when riding in wet or gritty off-road conditions.
You should choose the length based on your current chain's link count or your bike's specific drivetrain geometry. The 126-link version is standard for most mountain bikes, while the 138-link option is intended for bikes with longer chainstays or specific high-pivot suspension designs.
Yes, you can use a standard chain tool to remove excess links to reach your desired length. Just ensure your tool is compatible with 12-speed chains to avoid damaging the side plates.
