Advantages of 4mm Inward Offset Narrow-Wide Chainring
The inward offset narrow-wide chainring, when installed, aligns with the factory-set chainline of the crank.
This means that when the chain is on the middle sprocket of the rear derailleur, the chainline is parallel to the designed chainline of the bike frame (cassette centerline).
The chain’s deflection angle is symmetrical when on the largest and smallest cassette sprockets, significantly reducing wear on the narrow-wide chainring and minimizing chain noise.

The combination of a 7075 adapter plate and 7075 aluminum alloy teeth ensures an offset of 4mm for the narrow-wide chainring.
Applicable to various crank models, compatible with BCD110 double, BCD110 single, BCD130 triple, etc.
The larger adaptability allows the use of 7075 adapter plates to facilitate part replacements, or swapping adapter plates and the crank with different mounting hole orientations.
STONE offers more than just the fully aluminum closed single chainring with a 4mm inward offset. Another option features a combination of a carbon fiber plate and an aluminum alloy chainring. This design is lighter in weight while maintaining sufficient strength. It has been on the market for over two years and has gained recognition from many customers.
