PASS QUEST SRAM 8-Bolt Narrow-Wide Chainring

Enhanced Chain Retention. Lightweight Strength. Precision CNC Engineering.

The PASS QUEST SRAM 8-Bolt Direct-Mount Narrow-Wide Chainring is precision CNC-machined from high-strength 7075-T651 aerospace-grade aluminum alloy.

Featuring an extended 8.5 mm tooth profile, an optimized hollowed-out rear structure, and carefully chamfered details, this chainring is designed to deliver reliable chain retention and excellent structural rigidity while minimizing unnecessary weight.

1. Precision CNC-Machined Hollow Construction

Manufactured from a solid aluminum alloy plate using precision CNC machining, the chainring features an optimized hollowed-out rear structure.

The backside is carefully machined with hollow sections and chamfered edges to reduce unnecessary material while maintaining structural strength and rigidity.

This construction provides an excellent balance of lightweight performance and durability.

2. Extended 8.5 mm Narrow-Wide Tooth Profile

Featuring an extended tooth profile with an optimized height of 8.5 mm, this chainring is designed to improve chain engagement and retention.

The extended teeth reach deeper into the chain links, helping maintain secure chain contact and reduce the risk of chain drops during rough terrain, intense vibration, and demanding riding conditions.

3. High-Strength 7075-T651 Aerospace-Grade Aluminum Alloy

Precision-machined from high-strength 7075-T651 aerospace-grade aluminum alloy, this chainring offers an excellent balance of strength, rigidity, and durability.

The surface undergoes an anodizing process to improve corrosion resistance and protect the aluminum while providing a refined metallic finish.

4. Lightweight Chamfered Design

Carefully machined chamfers remove unnecessary material while maintaining structural integrity.

Combined with the hollowed-out rear structure, this design helps reduce overall weight and creates a clean, refined appearance with carefully finished edges and details.

5. Multiple Chainring Offset Options

Choose the appropriate offset according to your crankset, frame configuration, chainline, and chainring size.

• 3 mm Offset: Designed for compatible Boost frame setups.

• 6 mm Offset: Available for compatible 142 mm rear-spacing frame configurations.

• 0 mm Offset: An alternative for setups requiring a different chainline or additional frame clearance. It may also be suitable for certain larger chainring configurations.

Need Help Choosing the Right Offset?

Choosing the correct offset is essential for achieving proper chainline and sufficient frame clearance.

If you plan to install a larger chainring but are concerned about chainstay clearance, please contact PASS QUEST customer service before ordering.

We can guide you through the measurement process and help determine the maximum chainring size your frame can accommodate.

Important: Offset compatibility depends on your specific crankset, frame geometry, and chainring size. Please confirm your setup before purchasing.

6. Installation Instructions

A T25 Torx tool is required for installation.

Please ensure the chainring is correctly aligned with the crankset and securely installed before riding.

Follow the applicable crankset manufacturer's installation instructions and recommended tightening torque.
