PASS QUEST SRM 9 / SRM 7 110BCD 2x AERO Chainring Set

Precision Shifting. Lightweight Strength. Engineered for SRM Power Meters.

The PASS QUEST 110BCD 2x AERO Chainring Set is specifically designed for compatible SRM 9 and SRM 7 power meter systems.

Precision CNC-machined from high-strength aluminum alloy, this chainring set features a 5 mm thick aluminum plate, a distinctive triangular textured structure, and an optimized hollowed-out rear design.

Combining lightweight construction with excellent structural rigidity, this matched chainring set is engineered to deliver reliable chain engagement and smooth front-shifting performance.

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 carefully chamfered to reduce unnecessary material while maintaining structural strength and rigidity.

The large and small chainrings are designed as an integrated shifting system. Individual chainrings cannot be freely replaced with other models or mixed with incompatible designs.

2. High-Strength Aluminum Alloy – 5 mm Thick Construction

Manufactured from a 5 mm thick aluminum plate, the chainring set features a distinctive triangular and textured structure.

This carefully engineered design balances structural rigidity and weight reduction, providing reliable support for demanding road and gravel riding.

3. Smooth and Reliable Front Shifting

The matched large and small chainrings are designed to provide smooth and consistent front-shifting performance.

Their optimized tooth profiles and shifting structures help guide the chain during transitions between chainrings, allowing riders to select suitable gear ratios for different road conditions.

The 2x drivetrain configuration provides a wider range of gear combinations compared with a typical single-chainring setup, offering greater flexibility for different riding conditions.

4. Specially Designed Shifting Pins

The specially shaped shifting pins are designed to guide the chain during front shifting.

Their carefully positioned design helps improve chain pickup and engagement, supporting more precise and reliable gear changes.

5. Lightweight Hollowed-Out Design

Extensive hollowing and chamfering help reduce unnecessary weight while maintaining structural rigidity.

The triangular textured structure further contributes to the chainring's strength, creating a balance between lightweight performance and durability.

6. SRM Power Meter Compatibility

Designed specifically for compatible SRM 9 and SRM 7 power meter systems with a 110BCD mounting interface.

Important: Please confirm your exact SRM power meter model and mounting interface before ordering. Not all 110BCD power meters or spiders are compatible with this product.

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 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 power meter manufacturer's installation instructions.

Precision Component Notice

Chainring bolts are precision components.

Incorrect installation, improper alignment, or excessive tightening torque may damage the mounting hardware or chainring.

Please follow the installation instructions carefully. Damage caused by improper installation or incorrect use is not covered under warranty.

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 the following specifications:

• Exact SRM 9 or SRM 7 power meter model

• 110BCD mounting interface

• Required large and small chainring tooth combination

• Chain compatibility
