Derailleur hangers are frame-specific, not universal. You must visually compare your current hanger to the product imagery provided to ensure the bolt pattern and shape match exactly, as even slight variations can prevent proper installation.

Yes, this hanger is CNC machined from high-grade aluminum, which often provides better structural integrity and tighter tolerances than the original cast or stamped factory component.

A new hanger can sometimes shift the alignment of your derailleur slightly. After installation, you should perform a standard derailleur adjustment, specifically checking your limit screws and cable tension to ensure smooth gear changes.
