Product Description

PASS QUEST X110BCD Narrow-Wide 1x Road Chainring

The PASS QUEST X110BCD is a lightweight narrow-wide chainring designed for compatible 110 BCD Shimano-style 4-arm road cranksets and selected power meter setups.

CNC-machined from 7075-T651 aluminum alloy, the chainring combines high strength, low weight and a clean full-profile design for performance-oriented road, TT and custom 1x builds.

Its extended narrow-wide tooth profile improves chain retention and helps reduce the chance of chain drop during high-cadence riding or rough road conditions.

Available from 36T to 60T, making it suitable for a wide range of road, time trial, training and 1x drivetrain configurations.

CNC-Machined 7075-T651 Aluminum

The X110BCD chainring is CNC-machined from a solid piece of 7075-T651 aluminum alloy.

The rear surface is extensively machined and chamfered to remove unnecessary material while maintaining structural strength.

Key Benefits

• High-strength 7075-T651 aluminum alloy
• Full CNC-machined construction
• Lightweight hollowed rear design
• Chamfered machining for weight reduction
• High rigidity for efficient power transfer
• Suitable for performance road and 1x builds

Narrow-Wide Tooth Profile

The chainring uses an extended narrow-wide tooth design.

Alternating narrow and wide teeth provide improved chain engagement, helping the chain remain securely positioned on the chainring.

This design helps reduce:

• Chain movement
• Unwanted chain drop
• Chain instability during high cadence
• Chain retention issues on 1x setups

Ideal for riders converting a compatible road crankset to a single-chainring / 1x drivetrain.

Compatibility

Designed for selected 110 BCD 4-arm road cranksets, including compatible versions of:

• Shimano Claris R2000
• Shimano Sora R3000
• Shimano Tiagra 4700
• Shimano 105 5800
• Shimano Ultegra 6800
• Shimano Dura-Ace 9000
• Shimano Dura-Ace R9100
• XCADEY compatible power meter setups
• SIGEYI compatible power meter setups

Important Compatibility Notice

Shimano-style 110 BCD 4-arm cranksets have multiple generations with different mounting profiles.

110 BCD alone does not guarantee compatibility.

Please compare your crank spider shape with the product photos before ordering.

Shimano 4-Arm Generation Guide

Different Shimano generations use different spider shapes.

FC-5800 / FC-6800

Four mounting arms use a relatively simple profile without the additional curved relief sections found on later generations.

FC-R7000 / FC-R8000 / FC-R9100

The upper-right mounting area includes a different curved profile.

FC-R7100 / FC-R8100 / FC-R9200

The upper-right and lower-right mounting areas use another revised curved profile.

Because these generations differ in shape, chainrings designed for one generation may not fit another even when both are labeled 110 BCD.

Please confirm the exact crank model before ordering.

Not Compatible

Not compatible with:

• PASS QUEST PR5 120 BCD cranks
• PASS QUEST PR6 120 BCD cranks
• Other 120 BCD cranksets
• SRAM AXS-specific chains

120 BCD cranksets cannot use this 110 BCD chainring.
