⚠️ Important Correction (Chain Compatibility)
Your description says:
“Compatible with Shimano IG-chains”
This is not quite correct.
- ✅ The HG400 is designed for HG (Hyperglide) 9-speed chains
- ⚠️ IG chains are older and not recommended for optimal performance
???? For best results, use a Shimano HG 9-speed chain (e.g. HG53, HG93).

???? Final Take
The HG400 hits a sweet spot:
- More refined than entry-level cassettes
- Not as expensive as high-end race options
- Tough enough for everyday trail riding
