Coating Options

DLC (Diamond-Like Carbon) Coating - Lowest Friction

• Very low friction coefficient (<0.1)
• Extremely smooth shifting
• High surface hardness
• Suitable for Shimano and SRAM drivetrains
• Best for racing and performance builds

Note:
Due to the very low-friction surface, shifting impact may feel stronger and slightly louder compared to PVD coating. This is normal for DLC-coated components.
Colour coating is done by anodising, colour surface may wear and tear over time normal used.

We suggest new cassette pair with new Shimano Dura Ace chain to get best shifting experience.Enhanced PVD Coating - Maximum Durability

• Higher wear resistance
• Longer service life
• Lower running noise
• Optimised for Shimano drivetrains
• Ideal for training and high mileage use

Installation Recommendation
For the best shifting performance and lowest noise, install a new chain together with the cassette.

Pairing a new cassette with a worn chain is the primary cause of drivetrain noise and can lead to premature wear of both components.

Important note:

When install new chain, please make sure the chain length is correct trim, chain too short will cause high tension and affect shifting performance.

Recalibrate for High Low adjust screw, B-limit screw,and re-index gear is required, not plug and play. If user not confident for perform tuning, please look for nearby professional bikeshop for assistance.

Most of shifting issue are cause by incorrectly install and tuning.

Waxed ,wax-base lube & dry lube may result in noticeable noise compare to wet lube.
