Shimano CS-HG400 9-speed road and mountain bike cassette

Optimise the performance of your drivetrain with the Shimano CS-HG400 9-speed cassette, a versatile cassette designed for both road bikes and mountain bikes fitted with a Shimano 9-speed drivetrain. Thanks to its Hyperglide design, it delivers smooth, fast and precise gear changes to effectively support the different phases of your cycling.

Available in several tooth combinations, the Shimano CS-HG400-9 allows you to tailor your bike’s gear ratio to your riding style, whether you’re looking for greater versatility on the road or a wider gear range for mountain bike climbs. Shimano indicates compatibility with 9-speed HG chains and the HG-M sprocket standard.

Shimano: a versatile cassette for road and mountain biking

The CS-HG400-9 features SHIMANO HYPERGLIDE technology, with specially designed profiles and ramps to facilitate smooth chain movement from one sprocket to another. This design helps to achieve smoother and more precise gear changes, particularly when shifting whilst pedalling.

This cassette is available in several gear ranges to suit different needs:

• 11–25 teeth: suitable for road-oriented use and relatively fast-paced routes.
• 11–28 teeth: an attractive balance between speed and versatility.
• 11–32 teeth: a versatile gear range for routes with more elevation gain.
• 11–34 teeth: suitable for more challenging climbs.
• 11–36 teeth: a wide range to make climbs easier.
• 12–36 teeth: also favours lower gear ratios with a 12-tooth start sprocket.

Which Shimano CS-HG400 cassette should you choose?

The choice of gear range depends mainly on the terrain you ride on and your skill level.

An 11-25T cassette is particularly well-suited to road cycling and flat or undulating routes where the aim is to maintain relatively close gaps between the gears.

The 11-28T is an excellent all-round choice.

For more undulating or mountainous routes, the 11-32T, 11-34T or 11-36T versions offer progressively greater ease on climbs. The large 32-, 34- or 36-tooth sprocket reduces the gear ratio, making it easier to pedal on steep climbs.

Technical specifications

In summary

Shimano ’s CS-HG400 9-speed road and mountain bike cassette is a reliable and versatile solution for 9-speed Shimano drivetrains. With its various gear ratios, ranging from 11-25T to 12-36T, it allows you to prioritise speed on flat terrain or, conversely, to use shorter gear ratios for hilly and mountainous routes.

Its Hyperglide technology, HG 9-speed compatibility and wide range of gear ratios make this cassette a particularly attractive option for servicing, refurbishing or upgrading a bike fitted with a Shimano 9-speed drivetrain.
