PASS QUEST SRAM 3-Bolt AXS Hollow Mountain Narrow-Wide Chainring

Enhanced Chain Retention. Lightweight Strength. Precision CNC Engineering.

The PASS QUEST SRAM 3-Bolt AXS Mountain 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 engineered to provide reliable chain retention and excellent structural rigidity while minimizing unnecessary weight.

1. Precision CNC-Machined Construction

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

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

This construction provides an excellent balance of lightweight performance and durability for demanding mountain biking.

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 against oxidation and everyday wear.

4. Lightweight Hollowed-Out and Chamfered Design

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

The refined chamfered edges also create a clean, three-dimensional appearance while contributing to the chainring's lightweight construction.

5. Chainring Offset Options & Frame Compatibility

Choose the appropriate chainring offset according to your rear hub spacing, frame configuration, crankset, and chainline requirements.

• 3 mm Offset – 148 mm Boost: Designed for compatible 148 mm Boost thru-axle mountain bike setups.

• 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.

• 0 mm Offset – 157 mm Super Boost / Additional Frame Clearance: Designed for 157 mm Super Boost downhill setups and compatible Boost 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 proper chainline and sufficient chainstay clearance.

If you plan to install a larger chainring or are concerned about frame clearance, 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: Rear hub spacing alone does not guarantee crankset or chainring compatibility. Please confirm your crankset model, frame configuration, chainline, and chainring size before purchasing.

6. Installation Instructions

A T20 Torx tool is required to tighten the mounting screws.

Please ensure that the chainring is correctly aligned with the crankset before tightening the mounting hardware.

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