PASS QUEST FSA / Cannondale / Brompton T Line Crankset Adapter Spider
Lightweight CNC Construction. Precision Fit. Refined Design.
The PASS QUEST Spider is precision CNC-machined from high-strength 7075-T651 aluminum alloy, combining lightweight construction, structural rigidity, and carefully refined details.
Available in different designs, including hollow, round, and star-shaped styles, this spider offers multiple appearance options while providing a secure mounting interface for compatible chainrings.
1. Multiple Design Options
Choose from three distinctive spider designs:
-
Hollow Design: Optimized cutouts for weight reduction.
-
Round Design: A clean, classic appearance.
-
Star Design: A distinctive geometric appearance.
Each design features carefully machined arms and smooth transitions between the spider and chainrings.
2. Precision CNC-Machined 7075-T651 Aluminum Alloy
Manufactured from high-strength 7075-T651 aluminum alloy using precision CNC machining.
The spider features carefully designed hollow sections and chamfered edges to reduce unnecessary weight while maintaining structural strength and rigidity.
The optimized arm structure provides reliable support for compatible single- and double-chainring configurations.
3. Specially Designed for Brompton T Line – 130BCD
The 5-arm 130BCD spider is specifically designed for compatible Brompton T Line crankset configurations.
It features an optimized offset and reinforced mounting areas to provide a secure and reliable mounting interface.
The specially designed structure helps accommodate compatible chainring configurations while maintaining a clean and integrated appearance.
Important: Please confirm your exact crankset model and mounting interface before ordering.
4. Refined Matte Anodized Surface
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.
The refined surface provides a more attractive appearance while helping protect the aluminum against oxidation and everyday wear.
5. Precision Countersunk Mounting Structure
The precision-engineered countersunk structure helps position the mounting hardware accurately and provides a secure contact interface.
Its carefully designed mounting surfaces help reduce unwanted movement and noise when correctly installed.
6. Mounting Bolt Specifications
130BCD Spider:
-
Chainring mounting bolts are included.
-
Bolts are precision CNC-machined from solid 7075-T651 aluminum alloy.
-
9 mm extended bolts are designed for compatible double-chainring configurations.
-
The extended design provides the required mounting length for the specified chainring arrangement.
-
Important Compatibility Note – 130BCD
The 130BCD spider is designed exclusively for 1x Narrow-Wide chainring setups. It is NOT compatible with 2x double-chainring configurations.
Please confirm your chainring type before ordering.
110BCD Spider:
7. BCD Explanation
BCD stands for Bolt Circle Diameter.
It refers to the diameter of the imaginary circle passing through the centers of the chainring mounting holes.
Please confirm the BCD specification of your chainring before ordering.
8. Installation Instructions for 2x Chainring Configurations
For the specified 2x installation arrangement, the component order from the frame side outward is:
-
Small Chainring
-
Crank Arm
-
Large Chainring
Ensure that all components are correctly aligned before tightening the mounting bolts.
Mounting Torque
Recommended Tightening Torque: 6–8 N·m
Excessive tightening torque may damage the bolts, threads, or mounting components.
