PASS QUEST Race Face Direct-Mount Hollow Narrow-Wide Chainring
Enhanced Chain Retention. Lightweight Strength. Precision CNC Engineering.
The PASS QUEST Race Face Direct-Mount Narrow-Wide Chainring is precision CNC-machined from high-strength 7075-T651 aerospace-grade aluminum alloy.
Featuring an extended 8.5 mm tooth profile, a hollowed-out rear structure, and carefully chamfered details, this chainring is designed to provide reliable chain retention and excellent structural rigidity while minimizing unnecessary weight.
1. Precision CNC-Machined Hollow 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 edges to reduce unnecessary material while maintaining structural strength and rigidity.
This construction provides an excellent balance of lightweight performance and durability.
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 Chamfered Design
Carefully machined chamfers remove unnecessary material while maintaining structural integrity.
Combined with the hollowed-out rear structure, this design helps reduce overall weight and creates a clean, refined appearance with carefully finished edges and details.
5. Offset and Frame Clearance Guidance
Choosing the correct chainring offset is essential for achieving proper chainline and sufficient frame clearance.
If you plan to change your chainring offset or install a larger chainring, please contact PASS QUEST customer service before ordering.
We can guide you through the measurement process and help determine the maximum chainring size your frame can accommodate.
Important: The appropriate offset depends on your crankset, frame geometry, existing chainline, and chainring size. Please confirm compatibility before purchasing.
6. Installation Instructions
Two small positioning marks on the back of the chainring indicate the crank-facing side.
During installation:
-
Locate the two small positioning marks on the back of the chainring.
-
Position the marked side toward the crank.
-
Rotate the chainring into the correct mounting position.
-
Secure the chainring using the appropriate mounting hardware.
Installation Tool: A dedicated chainring removal tool compatible with the specific crankset mounting interface may be required.
Please confirm the required tool for your crankset before installation.
