Product Description

PASS QUEST 110BCD Narrow-Wide 1x Road Chainring

The PASS QUEST 110BCD Narrow-Wide Chainring is designed specifically for compatible Shimano R7100, R8100 and R9200 4-arm road cranksets.

CNC-machined from high-strength 7075-T651 aluminum alloy, it combines a lightweight open structure with an extended narrow-wide tooth profile for improved chain retention, rigidity and efficient power transfer.

Available from 36T to 58T, making it suitable for lightweight 1x road, climbing, racing and custom drivetrain builds.

Designed for Shimano 12-Speed Road Cranks

Designed for compatible:

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

This version is shaped specifically around the newer-generation Shimano 4-arm crank profile.

Important Compatibility Notice

Shimano 110BCD 4-arm cranksets have gone through several generations.

110BCD does not mean all Shimano 4-arm chainrings are interchangeable.

Different generations use different mounting profiles:

FC-5800 / FC-6800
Earlier 4-arm profile without the newer curved relief sections.

FC-R7000 / FC-R8000 / FC-R9100
Upper-right mounting area uses a different curved profile.

FC-R7100 / FC-R8100 / FC-R9200
Upper-right and lower-right mounting areas use the newer curved profile.

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

Please confirm your exact crank model before ordering.

7075-T651 CNC Aluminum

The chainring is CNC-machined from 7075-T651 aluminum alloy, providing an excellent combination of:

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

The open CNC structure removes unnecessary material while maintaining structural support under pedaling load.

Lightweight Open Structure

The chainring uses a carefully optimized hollow structure rather than simply removing material.

This helps distribute pedaling forces across the chainring while maintaining:

• Structural stability
• Rigidity
• Durability
• Low overall weight

The sculpted design also gives the chainring a distinctive performance-oriented appearance.

Extended 8.5mm Narrow-Wide Teeth

The tooth height is approximately:

8.5mm

The extended tooth profile provides deeper chain engagement to help reduce chain drop caused by:

• Road vibration
• Chain movement
• High cadence
• Sprinting
• Hard acceleration

The narrow-wide profile improves chain retention for 1x road drivetrain setups.

1x Road Drivetrain Design

Designed for riders converting compatible Shimano road cranks to a clean single-chainring / 1x drivetrain.

Suitable for:

• Road bikes
• Race builds
• Climbing setups
• Training bikes
• Lightweight builds
• Custom drivetrain configurations

Chain Compatibility

Compatible with standard:

9 / 10 / 11 / 12-Speed Chains

Please confirm your chain and drivetrain combination before ordering.
