7075 Aluminum Alloy

The chainring is manufactured from high-strength 7075 aluminum alloy, providing an excellent balance between lightweight performance and structural rigidity.

Main advantages:

High strength-to-weight ratio Good structural stiffness Excellent machining precision Lightweight construction Suitable for performance-oriented bicycles Full CNC Machining

The chainring is precision machined using CNC technology to provide accurate tooth geometry and consistent dimensions.

The CNC process helps improve:

Tooth profile accuracy Chain engagement Surface consistency Installation precision Power transmission efficiency AERO Hollow Design

The aerodynamic-style structure combines a clean appearance with optimized CNC hollow machining.

The design helps reduce unnecessary material while maintaining structural support around key load-bearing areas.

Advantages include:

Lightweight construction Modern AERO appearance High structural rigidity Efficient power transmission Narrow-Wide Tooth Profile

The alternating narrow and wide tooth design improves chain engagement and helps keep the chain securely positioned on the chainring.

This design helps provide:

Improved chain retention Reduced risk of chain drop Stable pedaling under load Smooth chain engagement Reliable 1X drivetrain performance 3mm Offset

The chainring features a 3mm offset.

Correct offset is important for maintaining proper chainline and drivetrain performance.

Before purchasing, please confirm that your crankset and frame require a 3mm offset chainring.

Incorrect offset may result in:

Poor chainline Increased drivetrain noise Abnormal chain wear Reduced shifting performance Frame or chainstay interference 34T–58T Wide Range

The GOLDIX 8-Bolt chainring is available in a wide range of tooth counts from 34T to 58T.

Smaller Sizes: 34T–40T

Suitable for riders who prioritize:

Easier climbing Higher cadence Lower gearing Mixed terrain Medium Sizes: 42T–48T

Provides a balanced combination of:

Speed Climbing ability Daily riding versatility Larger Sizes: 50T–58T

Suitable for riders who prioritize:

High-speed road riding Time trial style setups Flat-road performance Higher top-end gearing 10–12 Speed Compatibility

Designed for compatible:

10-Speed / 11-Speed / 12-Speed drivetrain systems

Please confirm your chain specification before purchasing.

For best performance, the chain width and drivetrain speed should match the selected bicycle setup.

Important Chain Compatibility Notice

This chainring is designed for standard compatible 10–12 speed chains.

It is not compatible with certain special 12-speed flat-top chain systems.

Please carefully check your chain type before ordering.

Using an incompatible chain may cause:

Poor tooth engagement Excessive drivetrain noise Chain skipping Accelerated wear Installation incompatibility 8-Bolt Direct Mount Interface

This product is designed specifically for compatible 8-Bolt Direct Mount cranksets.

Please note:

8-Bolt, 3-Bolt and other direct-mount interfaces are NOT interchangeable.

Before ordering, compare your original crank interface with the product images carefully.

Before Ordering, Please Confirm

Please check the following specifications:

8-Bolt direct-mount interface 3mm offset 34T–58T tooth count 10 / 11 / 12 speed drivetrain Chain type Required chainline Crank compatibility Frame clearance Chainstay clearance

Incorrect interface, offset or chain selection may result in installation failure.
