Full details
The Shimano Altus CS-HG400 7-speed cassette, with an 11-28T gear range, is designed for cyclists seeking reliable performance for daily use and general riding.

FAQs
What type of hub body do I need for this cassette?
This Shimano CS-HG400 cassette requires a Shimano HG-M (HyperGlide) freewheel body. It will not fit on older Uniglide freehubs or Campagnolo freehubs.
Is this cassette compatible with an 8-speed or 9-speed shifter and derailleur?
No, this is a 7-speed cassette and is designed to work with 7-speed shifters and derailleurs. Using it with 8 or 9-speed systems will result in poor shifting performance.
How do I clean the cassette?
Use a degreaser and a stiff brush to clean each cog individually. Rinse thoroughly with water and dry completely before lubricating the chain.
What is the gear range of this cassette?
The gear range is 11-28T, meaning the smallest cog has 11 teeth and the largest cog has 28 teeth.
Can I use this cassette for mountain biking?
Yes, the 11-28T range is suitable for general trail riding and less demanding mountain biking. For steeper climbs or more aggressive riding, a cassette with a larger climbing gear (e.g., 30T or 32T) might be preferable.
Do I need special tools to install this cassette?
Yes, you will need a cassette lockring tool and a chain whip to remove the old cassette and install the new one.
Troubleshooting
Skipping gears or poor shifting
Check derailleur adjustment (cable tension and limit screws). Ensure the cassette is correctly installed on the freewheel body. Inspect the chain for wear and replace if necessary.
Cassette not mounting correctly
Verify that you have an HG-M freewheel body. Ensure no debris is present on the freewheel body splines or the cassette's internal splines.
Excessive noise during pedaling
Clean the cassette and drivetrain thoroughly. Check that the cassette lockring is tightened properly. Inspect for any bent teeth or damage on the cogs.

Cons

Setup, Compatibility & Care
Compatibility: This cassette is specifically designed for 7-speed drivetrains and requires a Shimano HG-M (HyperGlide) freewheel body on your rear wheel hub. It is not compatible with Campagnolo freehubs or Shimano's older uniglide systems.
Setup: Installation requires a cassette lockring tool and a chain whip. Ensure the cassette is seated correctly on the HG-M splines. Proper derailleur adjustment and chain tension are crucial for optimal shifting performance.
Care: Regular cleaning is essential. After rides, especially in wet or muddy conditions, wipe down the cassette with a degreaser and a brush to remove dirt and grime. A clean drivetrain operates more efficiently and lasts longer. Periodically inspect the teeth for wear.
