Shimano CN-M8100 12 Speed chain XT

Designed for ultimate performance with the Deore XT M8100 drivetrain system, the XT CN-M8100 12-speed chain offers improved chain engagement and retention. The Shimano XT features Hyperglide +, allowing a seamless inward and outward shift that is faster with less shift. For quicker and more precise shifts, you now need less effort for the chain to engage in with the next cog, while shifting up or down.

Every chain includes Shimano's new quick link, for tool-less chain removal and installation, making on-the-trail repairs easier than ever before.


  • Features Shimano's SIL-TEC ultra-low friction surface treatment
  • Shimano Quick-Link included (SM-CN910-12)

    It�s a chain!

    In upgrading my bike to a 12-speed, electronic system, I needed a new chain. This one works!

    Exactly what I needed
    by Anonymous

    No surprises here. I received exactly what I was looking for, unlike when buying from other sources. This chain is quiet, smooth, and has nice longevity. I�ve been waxing and riding on this chain for about 4 months now with no real signs of wear or issue.

    The new XT 12-speed system is the quietest, smoothest yet. While SRAM certainly works well, it is notably louder. I own both but do enjoy the quiet of XT.

    I bought 2 - one to ride (road bike) and one for the tool box. Quiet, quick, sturdy.
