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.

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

Recommended Chains
Shimano Dura-Ace 12s
SUMC 12s

For best performance with SRAM AXS, Shimano 12-speed chains are recommended.

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.
