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.

  • Not designed for use with a front derailleur.

Mounting Bolts and Tightening Torque

Standard mounting screws are provided free of charge.

Recommended Tightening Torque: 6–8 N·m

Excessive tightening torque may damage the screws, threads, or mounting components.

Use an appropriate torque wrench and follow the crankset manufacturer's installation instructions.

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.

 


FAQ

Continuous upgrading and optimization


We have more colorful custom-designed products.

This product comes in two colors and is a limited edition, so we don't have a link to it.

If you are interested in a customized product, you can contact customer service to inquire about the number of teeth, price, and our stock availability.
We will reply to you as soon as possible.

You can also email wangchan1013@gmail.com for more details.

If you are a bicycle shop owner, please contact customer service and provide the relevant documents. We will offer you a discounted price.

Looking for top-level professional cyclists

This is the new equipment for professional road bikers, track bikers, and time trial riders.

We designed and manufactured a 5mm thick narrow-wide chainring, increasing lateral stiffness and featuring a high bracket density. It weighs about the same as a carbon fiber chainring with the same number of teeth, but is much stiffer, making it suitable for riders with higher power output.

Our single-speed chainring has also been optimized and upgraded.
