PASS QUEST 104BCD AXS Round Narrow-Wide Chainring
Enhanced Chain Retention. Lightweight Strength. Precision CNC Engineering.
The PASS QUEST 104BCD Round Narrow-Wide Chainring is precision CNC-machined from high-strength 7075-T651 aluminum alloy.
Featuring an extended 8.5 mm tooth profile, an optimized hollowed-out rear structure, and precision 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.
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 Aluminum Alloy
Precision-machined from high-strength 7075-T651 aluminum alloy, this chainring offers an excellent balance of strength, rigidity, and durability.
The material provides reliable structural support while maintaining a lightweight construction suitable for demanding cycling conditions.
4. Refined Matte Anodized Surface Finish
7075 aluminum alloy presents challenges during the anodizing process.
Through multiple rounds of prototyping and surface-finishing improvements, we refined the anodizing process to achieve a consistent matte anodized finish.
Compared with a conventional sandblasted finish, the refined matte surface provides a more attractive appearance while helping protect the aluminum against oxidation and everyday wear.
5. Lightweight Hollowed-Out and Chamfered Design
Extensive hollowing and carefully machined chamfers help reduce unnecessary material while maintaining structural rigidity.
The carefully finished edges and corners create a distinctive three-dimensional appearance, combining lightweight construction with a refined design.
6. Precision Countersunk Mounting Structure
The precision-engineered countersunk structure provides a secure mounting interface and helps position the chainring accurately.
Its carefully designed contact surfaces help maintain stable mounting, while the clean installation finish contributes to reduced unwanted movement and noise when correctly installed.
7. 1x Single-Chainring Drivetrain Only
This Narrow-Wide chainring is designed exclusively for 1x single-chainring drivetrains.
-
Suitable for 1x drivetrain configurations.
-
Not suitable for 2x double-chainring systems.
-

Before You Order
Please confirm your exact crankset model, 104BCD mounting interface, chain compatibility, and drivetrain configuration before purchasing.
Important: A 104BCD mounting standard alone does not guarantee compatibility with every SRAM AXS crankset. Please verify your exact crankset model and mounting interface before ordering.
If you are unsure about compatibility, contact PASS QUEST customer service before placing your order.
