Shimano Dura-Ace CN-HG901-11 Chain - 11-Speed | 116 Links

Why Do Serious Riders Choose the Shimano Dura-Ace CN-HG901-11 Chain?

The CN-HG901-11 is Shimano's flagship 11-speed road chain, engineered to the same performance standard as the Dura-Ace groupset it was designed for. The SIL-TEC surface treatment embeds fluorine molecules into the outer plates through an advanced plating process, reducing inter-link friction and extending wear life compared to standard nickel-plated chains. The result is a chain that runs quieter, shifts more crisply, and resists elongation longer under the sustained load of hard training and racing miles.

The asymmetric plate design is optimized for directional engagement, so front shifts from small to large ring and rear shifts across the cassette are smooth in both directions under power. At 116 links the CN-HG901-11 ships ready to install on road and gravel builds without additional link removal for most setups. It is compatible with any Shimano 11-speed road drivetrain including Dura-Ace R9100, Ultegra R8000, and 105 R7000, and meets Shimano e-bike durability requirements for added versatility. For riders who demand the full Dura-Ace experience from lever to cog, this chain completes the picture.
