PASS QUEST SRAM 8-Bolt AXS AERO Mountain Narrow-Wide Chainring

Enclosed AERO Design. Enhanced Chain Retention. Lightweight Strength.

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

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

1. Precision CNC-Machined Enclosed AERO Construction

Manufactured from a solid aluminum plate using precision CNC machining, this chainring features a distinctive enclosed AERO design.

The rear structure is carefully hollowed out and chamfered to reduce unnecessary material while maintaining structural strength and rigidity.

The enclosed construction provides additional structural support with minimal additional weight, making it suitable for demanding mountain biking and high-intensity riding.

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 Hollowed-Out and Chamfered Design

The rear structure features carefully optimized hollowing and extensive chamfering to reduce unnecessary material while maintaining structural integrity.

The refined chamfered edges also create a clean, three-dimensional appearance.

This design combines lightweight construction with the rigidity required for demanding mountain biking.

5. Chainring Offset Options & Frame Compatibility

Choose the correct chainring offset according to your rear hub spacing and frame configuration.

• 6 mm Offset – 135 mm QR / 142 mm Non-Boost: Designed for traditional 135 mm quick-release and 142 mm non-Boost thru-axle setups.

• 3 mm Offset – 148 mm Boost: Designed for 148 mm Boost thru-axle frames, a widely used standard for modern mountain bikes.

• 0 mm Offset – 157 mm Super Boost / Additional Frame Clearance: Designed for 157 mm Super Boost downhill setups and compatible configurations requiring additional chainring-to-frame clearance, particularly when using larger chainrings.

Need Help Choosing the Right Offset?

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

If you plan to install a larger chainring or are unsure which offset is suitable for your frame, please contact PASS QUEST customer service before ordering.

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

Important: Please confirm your crankset, rear hub spacing, frame configuration, and chainring size before purchasing. Rear hub spacing alone does not guarantee crankset or chainring compatibility.

6. Installation Instructions

A T25 Torx tool is required to tighten the mounting screws.

Please ensure that 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.
