PASS QUEST Shimano X110BCD 4-Bolt AERO Round Narrow-Wide Chainring
Enhanced Chain Retention. Lightweight Strength. Precision CNC Engineering.
The PASS QUEST Shimano X110BCD Round Narrow-Wide Chainring is precision CNC-machined from high-strength 7075-T651 aluminum alloy.
Featuring an extended 8.5 mm tooth profile, a distinctive triangular textured structure, and an optimized hollowed-out rear design, this chainring is engineered to deliver 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. 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.
Its distinctive triangular and textured structure is carefully engineered to enhance stiffness while maintaining a lightweight construction.
3. 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.
4. Refined 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 and worked with a specialized manufacturing facility in Taiwan to achieve a consistent, high-quality finish.
The anodized surface helps protect the aluminum against oxidation and everyday wear while providing a refined appearance.
5. 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 striped details and refined chamfered edges create a distinctive three-dimensional appearance while balancing weight reduction and rigidity.
6. Drivetrain Compatibility – 1x Only
This Narrow-Wide chainring is designed exclusively for 1x single-chainring drivetrains.
