Recommendations
- Before installation, make sure the freehub body is clean, undamaged and compatible with the cassette
- Install the cassette onto the freehub, carefully aligning the spline profiles and ensuring that the cassette is fully seated
- Install the supplied lockring and tighten it using a suitable cassette tool and a torque wrench
Lockring tightening torque: 40 Nm - After installation, check that the cassette is securely mounted with no lateral play
- Verify correct rear derailleur adjustment before riding
- For best shifting performance, use a new compatible Shimano 12-speed chain with your new ALUGEAR cassette
- A worn or excessively stretched chain can significantly reduce shifting quality and accelerate cassette wear
Regularly inspect the cassette and chain for wear. Replacing a worn chain in time will help extend the service life of the cassette - Keep the cassette and chain clean and properly chain lubricated
- Periodically remove dirt and drivetrain residue using a neutral bicycle drivetrain cleaner
- Avoid aggressive chemicals that may damage the surface treatment or anodized aluminium components
