Product Description

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

The PASS QUEST 110BCD Full-Profile Narrow-Wide Chainring is designed 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, the chainring uses a full-profile design with strategically machined and chamfered sections to balance rigidity, durability and weight.

Available from 44T to 60T, it is designed for riders looking for a larger 1x road chainring with a clean, integrated appearance.

Shimano R7100 / R8100 / R9200 Compatibility

Designed for compatible:

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

The mounting profile is specifically designed around the newer-generation Shimano 4-arm crank shape.

Important Compatibility Notice

Shimano 110BCD 4-arm cranksets use different mounting profiles depending on generation.

FC-5800 / FC-6800
Earlier 4-arm design without the newer curved mounting profile.

FC-R7000 / FC-R8000 / FC-R9100
Different profile with a curved section at the upper-right mounting area.

FC-R7100 / FC-R8100 / FC-R9200
Newer profile with curved sections at both the upper-right and lower-right mounting areas.

This product is designed for the R7100 / R8100 / R9200 generation.

Please confirm your exact crank model before ordering. 110BCD alone does not guarantee compatibility.

Full-Profile CNC Construction

Unlike a heavily open or skeletonized chainring, this version uses a full-profile design for a clean appearance and high structural rigidity.

The chainring is CNC-machined from a solid aluminum plate, with strategic machining on the rear and around selected areas to remove unnecessary material.

This provides:

• High rigidity
• Stable power transfer
• Clean full-profile appearance
• Optimized weight
• Durable construction

7075-T651 Aluminum Alloy

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

The material and structural design provide an excellent balance of:

• Strength
• Rigidity
• Low weight
• Wear resistance
• Long-term durability

The triangular and textured structural sections are designed to maintain stiffness under pedaling load for direct power transfer.

Narrow-Wide Tooth Design

The narrow-wide tooth profile provides improved engagement between the chain and chainring.

This helps reduce the risk of chain drop caused by road vibration, chain movement and aggressive pedaling.

Designed for 1x road drivetrain setups where reliable chain retention is especially important.

Refined Tooth Profile

PASS QUEST developed the tooth profile through repeated testing and optimization.

The design focuses on:

• Smooth chain engagement
• Tooth durability
• Chain pin positioning
• Chain groove alignment
• Stable chain retention

The goal is to provide smooth drivetrain operation while maintaining reliable chain engagement.

Lightweight CNC Optimization

Weight reduction is achieved through carefully positioned machining rather than simply removing large amounts of material.

Strategic machining and chamfering help maintain chainring rigidity while reducing unnecessary mass.

The result is a full-profile chainring that balances:

Rigidity · Weight · Durability · Appearance

Recessed Mounting Structure

The recessed mounting interface is designed to increase the effective contact area between the chainring and crank.

This helps provide:

• Accurate positioning
• Secure installation
• Cleaner fit
• Reduced fitment variation
