PASS QUEST 110 BCD 5-Bolt AERO 2x Chainring Set

Smooth Shifting. Lightweight Construction. Precision Engineering.

The PASS QUEST 110 BCD 5-Bolt 2x Chainring Set is precision CNC-machined from high-strength 7075-T651 aluminum alloy.

Featuring an extended 8.5 mm tooth profile, a carefully engineered triangular structure, and a hollowed-out rear design, this chainring set combines structural rigidity with lightweight performance.

The matched large and small chainrings are designed to work together as an integrated shifting system, helping deliver smooth and reliable front shifting.

Key Features

1. Precision CNC-Machined Construction

Manufactured from a solid aluminum plate using precision CNC machining, the chainring set features an optimized structure.

The reverse side is extensively hollowed out and chamfered to reduce unnecessary material while maintaining structural strength and rigidity.

2. High-Strength 7075-T651 Aluminum Alloy

Made from high-strength 7075-T651 aluminum alloy, the chainring features a distinctive triangular and textured structure designed to enhance rigidity while maintaining a lightweight construction.

3. 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 original sandblasted anodized finish into a more refined matte anodized finish.

The result is a smoother, more sophisticated surface appearance with enhanced resistance to oxidation and everyday wear.

4. Extended 8.5 mm Tooth Profile

The extended tooth profile is designed to improve chain engagement and retention.

With an optimized tooth height of 8.5 mm, the chainring helps maintain chain engagement during vibration, demanding riding conditions, and high-load pedaling.

5. Precision Countersunk Mounting Structure

The carefully engineered countersunk structure provides accurate positioning and a secure mounting interface.

Its integrated design creates a cleaner installation appearance and helps minimize unwanted movement and noise when correctly installed.

Compatibility

Designed for compatible 110 BCD 5-bolt cranksets, including selected models from:

• SRAM RED

• SRAM FORCE

• SRAM RIVAL

• SRAM S350

• SRAM S900

• ROTOR

Important: Compatibility depends on the exact crankset model, mounting interface, and chainring configuration. Please confirm your specific crankset before ordering.

Important: Original PASS QUEST Matched Pair Required

The large and small chainrings are precision-matched and designed to work together as a complete PASS QUEST 2x chainring set.

Both chainrings must be used together as the original PASS QUEST matched pair.

Do not mix chainrings from different brands or combine incompatible tooth combinations. Doing so may result in poor shifting performance, unreliable gear changes, or drivetrain compatibility issues.

For optimal shifting performance, always use the complete original PASS QUEST 2x chainring set.

Mounting Bolts and Tightening Torque

Standard mounting bolts are provided free of charge.

Recommended Tightening Torque: 6–8 N·m

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

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

Installation Instructions

Follow these steps to correctly align the chainrings:

1. Position the Large Chainring: Align the positioning pin on the large chainring directly beneath the crank arm.

2. Align the Small Chainring: Position the alignment mark on the small chainring directly beneath the crank arm.

3. Align the Mounting Holes: Match the countersunk holes with the corresponding chainring bolt positions.

4. Secure the Chainrings: Install the mounting bolts and tighten them evenly according to the recommended torque specifications.

Check that both chainrings are correctly aligned before completing installation.

Before You Order

Please confirm your crankset model, 110 BCD 5-bolt mounting interface, and required large and small chainring tooth combination before purchasing.

If you are unsure about compatibility, contact PASS QUEST customer service before placing your order.
