FAQ

What is the difference between the CN-HG40 and CN-HG71?

Both are designed for 6, 7, and 8-speed Shimano drivetrains. The CN-HG71 is also e-bike rated. The CN-HG40 is the standard non-e-bike chain for this speed range and is appropriate for most conventional drivetrains.

Is the CN-HG40 compatible with SRAM and other brands running 8-speed?

Generally yes. 8-speed chains are broadly compatible across brands, but Shimano-to-Shimano remains the safest specification for optimal shifting performance.

Does the CN-HG40 include a connecting pin?

No. A Shimano connecting pin or compatible quick-link must be purchased separately.

Best For

Commuters, casual riders, and budget bike owners maintaining a 6, 7, or 8-speed Shimano drivetrain who need a correct OEM-specification replacement chain.
