PASS QUEST Full-Profile 110BCD Narrow-Wide Chainring for Shimano R7100 / R8100 / R9200 | 42T–60T

PASS QUEST Full-Profile 110BCD Narrow-Wide Road Chainring

The PASS QUEST Full-Profile 110BCD Narrow-Wide Chainring is designed specifically for compatible Shimano 4-arm road cranksets, including 105 R7100, Ultegra R8100 and Dura-Ace R9200.

CNC-machined from a solid 7075-T651 aluminum plate, this full-profile chainring combines high rigidity, optimized weight and a clean aero-style appearance.

The narrow-wide tooth profile improves chain retention, while the refined tooth geometry is designed for smoother engagement, lower drivetrain noise and improved long-term wear resistance.

Available from 42T to 60T, making it suitable for road, race, TT and custom 1x drivetrain builds.

Designed for Shimano R7100 / R8100 / R9200

Fits compatible:

• Shimano 105 FC-R7100
• Shimano Ultegra FC-R8100
• Shimano Dura-Ace FC-R9200

Please confirm your exact crank model before ordering.

Full-Profile Aero Design

The chainring uses a full-profile closed design for a cleaner, more integrated appearance.

Compared with heavily skeletonized chainrings, the full-profile structure provides:

• High torsional rigidity
• Stable power transfer
• Clean aero-style appearance
• Improved structural support
• Premium integrated look

7075-T651 CNC Construction

The chainring is CNC-machined from high-strength 7075-T651 aluminum alloy.

This material provides an excellent balance of:

• High strength
• High rigidity
• Wear resistance
• Impact resistance
• Low weight
• Long-term durability

Optimized Lightweight Structure

Weight reduction is achieved through carefully controlled rear-side machining and thinning.

Rather than simply removing material, the structure is optimized to maintain rigidity under pedaling load.

This helps balance:

Weight · Rigidity · Durability · Appearance

Smooth Tooth Engagement

PASS QUEST states that the tooth profile was developed through repeated testing and refinement.

The design focuses on:

• Smooth chain engagement
• Stable chain-pin positioning
• Accurate chain groove alignment
• Reduced drivetrain noise
• Reduced tooth wear
• Consistent drivetrain operation

Narrow-Wide Tooth Design

The chainring uses a narrow-wide tooth profile for improved chain retention on 1x drivetrain setups.

The alternating tooth widths help keep the chain securely engaged during:

• High-cadence riding
• Sprinting
• Hard acceleration
• Road vibration
• Long-distance riding

Recessed Mounting Structure

The recessed mounting interface increases the effective contact area between the chainring and crank.

This helps provide:

• Accurate positioning
• Secure installation
• Improved fit
• Reduced unwanted movement

Optional Crank Covers

Matching decorative crank covers can be used for a cleaner and more integrated appearance.

They can also help reduce dirt and debris entering the crank-to-chainring interface.

Crank covers are not included unless specifically stated or selected.

For a cleaner 1x setup, you can add the matching PASS QUEST Chainring Bolt Cover Set for Shimano R9200 / R8100 / R7100 .
