Smooth Hyperglide Shifting
Shimano Hyperglide technology uses specially designed sprocket profiles to guide the chain efficiently between gears.
Combined with compatible shifters, derailleurs and a properly maintained chain, the CS-HG400-9 delivers dependable shifting for everyday cycling and rides on varied terrain.
Versatile 11-32T Gearing
The 11-32T configuration provides a wider gear range than the 11-28T version, making it particularly useful for climbing and riding on rolling terrain.
Its nine sprockets are arranged as follows:
11 – 12 – 14 – 16 – 18 – 21 – 24 – 28 – 32T
The 11-tooth smallest sprocket provides higher gearing for faster sections, while the 32-tooth largest sprocket makes climbing easier.
Compatibility
The CS-HG400-9 is designed for compatible Shimano HG splined freehub bodies and 9-speed shifting systems.
Before installation, confirm that the rear derailleur supports a 32-tooth largest sprocket and that its total capacity is appropriate for the bicycle's drivetrain.
This product is a cassette, not a threaded freewheel. It cannot be installed directly onto a threaded freewheel hub and is not compatible with Shimano Micro Spline freehub bodies.
Installation and Maintenance
Install the cassette using appropriate Shimano-compatible tools and tighten the lockring to the manufacturer's recommended torque of 30–50 N·m.
Inspect the chain for wear when replacing the cassette to maintain reliable shifting and drivetrain performance.
Note: This product is the Shimano CS-HG400-9 cassette in the 11-32T (ar) configuration.
