Product Description

PASS QUEST SPRILL 110BCD Narrow-Wide Road Chainring

The PASS QUEST SPRILL 110BCD Chainring is designed for compatible Shimano 4-arm road cranksets, including Dura-Ace FC-R9200, Ultegra FC-R8100 and 105 FC-R7100.

CNC-machined from high-strength 7075-T651 aluminum alloy, it combines a lightweight machined structure with high rigidity and a 3mm offset design for 1x road drivetrain applications.

Available from 40T to 58T, giving riders a wide range of gearing options for road, fast all-road and performance-oriented 1x builds.

Key Features

Compatibility

Designed for:

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

Important Compatibility Notice

Shimano 110BCD 4-arm cranksets have gone through several generations, and the shape around the mounting interface is different.

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

Older cranksets may use different mounting contours and are not necessarily interchangeable.

For reference:

• FC-5800 / FC-6800 – Different 4-arm profile
• FC-R7000 / FC-R8000 / FC-R9100 – Different mounting contour
• FC-R7100 / FC-R8100 / FC-R9200 – Current compatible profile shown

Please verify your exact crank model before ordering.

Specifications

Size & Weight

Weights are approximate and may vary slightly due to manufacturing and measurement differences.

3mm Offset for 1x Road Builds

The 3mm offset moves the chainring position to optimize the chainline for compatible 1x configurations.

A properly aligned chainline helps the drivetrain run more smoothly and reduces unnecessary lateral chain angle.

Because cranksets and frames vary, please verify chainline and frame clearance before installation.

Narrow-Wide Chain Retention

The alternating narrow-wide tooth profile closely matches the inner and outer links of the chain.

With an extended tooth height of approximately 8.5mm, the design increases chain engagement to help keep the chain securely seated during vibration and high-intensity riding.

Ideal for clean, lightweight 1x road drivetrain conversions.

High-Rigidity 7075-T651 Construction

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

Its structural layout uses reinforced sections around key load areas to maintain rigidity and provide direct power transfer under pedaling loads.

Strategically machined areas help remove excess material without unnecessarily compromising structural strength.

CNC Chamfered Design

Multiple machined sections and chamfered edges reduce unnecessary material while creating a clean, dimensional appearance.

The result is a chainring designed to combine:

Low Weight · High Rigidity · Precise Fit · Clean Aesthetics

Important Installation Note

This is an aftermarket 1x chainring.

Before ordering, please confirm:

• Crank model
• 110BCD 4-arm interface
• Required chainring size
• 3mm offset compatibility
• Frame clearance
• Chainline
