PASS QUEST 110/80BCD Chainring Set for Shimano GRX RX810 / RX820 | 2x 11/12-Speed 44/28T–52/36T

PASS QUEST 110/80BCD Chainring Set for Shimano GRX RX810 / RX820

Upgrade your gravel drivetrain while keeping your existing crankset with the PASS QUEST 2x Chainring Set for Shimano GRX RX810 / RX820.

Designed as a drivetrain-focused upgrade, this chainring combination uses a 110BCD outer chainring and 80BCD inner chainring, with five gearing options ranging from 44/28T to 52/36T.

Precision-machined from 7075-T651 aluminum, the chainrings are developed as a matched 2x system, with the outer ring, inner ring, tooth profiles and shifting zones designed to work together for smooth and reliable front shifting across demanding gravel and mixed-road conditions.

KEEP YOUR ORIGINAL GRX CRANKSET

This system is designed to upgrade the drivetrain without requiring replacement of the complete crankset.

It is intended for compatible Shimano GRX RX810 / RX820 configurations, allowing riders to retain their existing crank while changing the chainring combination to better suit their preferred gearing.

This makes it possible to customize the drivetrain around your riding style without unnecessarily replacing the complete crank assembly.

110BCD OUTER / 80BCD INNER

The PASS QUEST GRX chainring system uses two different bolt circle diameters:

Outer Chainring: 110BCD
Inner Chainring: 80BCD

The outer and inner chainrings are designed to function together as a matched 2x drivetrain system.

FIVE GEARING OPTIONS

Different terrain and riding styles require different gearing. PASS QUEST offers five chainring combinations to provide a broader range of drivetrain choices:

• 44/28T
• 46/31T
• 48/33T
• 50/34T
• 52/36T

From the climbing-oriented 44/28T combination to the higher-geared 52/36T setup, riders can select the combination that best matches their terrain, cadence and riding style.

DESIGNED AS A MATCHED 2x SYSTEM

Gravel riding places demanding requirements on front shifting performance due to constantly changing gradients, surfaces and riding conditions.

Rather than treating the two chainrings as independent components, PASS QUEST develops the outer ring, inner ring, tooth profiles and shifting zones as a coordinated system.

This approach is designed to provide predictable front shifting and practical gearing across real-world gravel and mixed-road riding conditions.

7075-T651 ALUMINUM

The chainrings are manufactured from high-strength 7075-T651 aluminum alloy, providing an excellent balance of low weight, rigidity and durability.

Precision machining is used throughout the chainring structure and tooth profiles to maintain accurate dimensions and a refined metallic finish.

ANODIZED SURFACE FINISH

The aluminum surface receives an anodized finish for improved surface durability and corrosion resistance while retaining the distinctive machined appearance of the chainring.

The precision-machined surfaces interact with light differently depending on the viewing angle, creating a clean and premium metallic finish.

Available Colors: Black / Silver

GRAVEL-FOCUSED GEARING

The wide range of available chainring combinations allows riders to tailor their drivetrain to different riding conditions.

44/28T provides a lower gearing range suited to climbing and demanding mixed terrain, while progressively larger combinations provide higher gearing for faster gravel, all-road and mixed-surface riding.

Select your gearing based on your terrain, riding style, cassette range and preferred cadence.
