Shimano Nexus CN-NX10 Chain - Single Speed 1/2" x 1/8" | 114 Links

What Bikes Use the Shimano Nexus CN-NX10 Single Speed Chain?

The CN-NX10 is a 1/2" x 1/8" single speed chain designed specifically for use with Shimano Nexus internally geared hubs and single speed drivetrains. At 114 links, it fits most standard urban, commuter, and city bike chainline setups. The chain uses Shimano's dacrotized treatment, a zinc-flake coating process that provides corrosion resistance significantly beyond standard zinc plating, making it well suited for year-round commuter use in wet climates where chain longevity is directly tied to how well the surface resists moisture and environmental exposure. This is not a decorative treatment — dacrotizing improves the chain's resistance to rust in the kind of conditions that eat through cheaper chains quickly.

The 1/8" inner width is the correct specification for single speed and internally geared hub setups, which use wider chainrings and cogs than multi-speed derailleur systems. Using a standard 3/32" multi-speed chain on a single speed drivetrain results in poor engagement and accelerated wear. The CN-NX10 is the factory-spec chain for Nexus hub-equipped bikes from Shimano and is the correct replacement for any single speed or Nexus-geared commuter, city, or utility bike. It is not compatible with derailleur drivetrains. For any rider replacing a worn chain on a Nexus internally geared hub or single speed setup, the CN-NX10 is the correct spec chain to maintain the drivetrain's original performance and longevity.
