• PASS QUEST Shimano 2x Fully Enclosed Chainring Set – 110 BCD

  Fully Enclosed Design. Precision Shifting. Refined Engineering.

  The PASS QUEST Shimano 2x Fully Enclosed Chainring Set is precision CNC-machined from a solid plate of high-strength aluminum alloy.

  Featuring a fully enclosed design, carefully optimized structural details, and specially shaped positioning pins, this double chainring set is engineered to provide coordinated shifting performance, reliable chain engagement, and a clean, integrated appearance.

  Key Features

  1. Fully Enclosed CNC-Machined Design

  Manufactured from a solid aluminum plate using precision CNC machining, the chainring set features carefully engineered material removal and chamfered edges.

  The refined structure helps reduce unnecessary weight while maintaining the rigidity required for reliable performance.

  2. Optimized Structure for Smooth Shifting

  The chainring structure and tooth engagement features are carefully designed to support smooth chain movement between the large and small chainrings.

  The optimized design aims to promote consistent shifting performance and help reduce chain noise and chain drops when used with a compatible drivetrain.

  3. Specially Designed Positioning Pins

  The specially shaped positioning pins are designed to guide the chain during front shifting, helping improve chain engagement and support smoother transitions between the two chainrings.

  Correct installation and alignment are essential for achieving the intended shifting performance.

  4. Versatile 2x Drivetrain Performance

  A double chainring system offers a wider range of gear ratios than many single-chainring configurations.

  By combining different front chainring sizes with the rear cassette, riders can select suitable gear ratios for climbing, flat roads, and high-speed riding.

  Shimano Crankset Compatibility

  Different generations of Shimano 110 BCD cranksets feature different mounting arm shapes. Please check your crankset carefully before ordering.

  

• FC-5800 / FC-6800: Four mounting arms without curved sections.

• FC-R7000 / FC-R8000 / FC-R9100: One curved section in the upper-right area.

• FC-R7100 / FC-R8100 / FC-R9200: Two curved sections, one in the upper-right area and one in the lower-right area.

Important: Please select the correct version according to your exact crankset model. Do not assume that all Shimano 110 BCD cranksets are interchangeable.

Important: Original PASS QUEST Matched Pair Required

The large and small chainrings are precision-matched and designed to work together as a complete PASS QUEST 2x set.

Both chainrings must be used together as the original PASS QUEST matched pair.

Do not mix chainrings from different brands or combine incompatible tooth combinations. Doing so may result in poor shifting performance, unreliable gear changes, or drivetrain compatibility issues.

For optimal shifting performance, always use the complete original PASS QUEST 2x chainring set.

2. Align the Small Chainring: Position the alignment mark on the small chainring directly beneath the crank arm.

3. Align the Mounting Holes: Match the countersunk holes with the corresponding chainring bolt positions.

4. Secure the Chainrings: Install the mounting bolts and tighten them evenly according to the recommended torque specifications.

Please check that both chainrings are correctly aligned before completing installation.

Mounting Bolts and Tightening Torque

Standard mounting bolts are provided free of charge.

Recommended Tightening Torque: 6–8 N·m

Excessive tightening torque may damage the bolts, threads, or mounting components. Use an appropriate torque wrench and follow the crankset manufacturer's installation instructions.

Precision Component Notice

Chainring bolts are precision components. Incorrect installation, cross-threading, or overtightening may cause damage.

Damage resulting from improper installation is subject to the applicable warranty terms.

Professional installation is recommended if you are unfamiliar with chainring installation.

Before You Order

Please confirm your exact Shimano crankset model, mounting interface, and required tooth combination before purchasing.
