Product Specifications

Choose the Correct Crankset Version

Please select the version according to your exact crankset model. The mounting structure differs between versions, so do not select by tooth count alone.

F71 Version: for Shimano 105 R7100

F81 Version: for Shimano Ultegra R8100

Important: The F81 full-cover version cannot be installed on an R8100-P power meter crank.

F92 Version: for Shimano Dura-Ace R9200

The F92 chainring is designed for Shimano Dura-Ace R9200 cranksets. It can also be installed on the for Shimano R9200-P power meter crank after the required modification procedure.

High-Strength AL7075-T651 Aluminum

The chainring is manufactured from high-strength AL7075-T651 aluminum alloy. The T651 temper treatment helps improve material hardness, dimensional stability, and machining accuracy.

The aluminum plate is stress-relieved before CNC machining to help reduce deformation during production and improve final chainring flatness. This supports accurate fitment and consistent drivetrain performance after installation.

Anodized Surface

The chainring receives an anodized surface treatment that forms a protective oxide layer on the aluminum surface. This improves:

• Corrosion resistance
• Wear resistance
• Surface hardness
• Color stability
• Long-term durability

Precision CNC Machining

The tooth profile and mounting structure are CNC machined for dimensional accuracy. The chainring features precision-machined tooth profiles, smooth transition radii, reinforced radial rib structure, controlled mounting dimensions, and high flatness accuracy.

For the 60T version, factory flatness is controlled to below approximately 0.3mm. Smaller tooth-count versions generally achieve even better flatness.

Chain Compatibility

Compatible with Shimano 9/10/11/12-speed chains and for SRAM 9-12-speed non-Flattop 12/13-speed chains.

for SRAM Flattop 12/13-speed Chain Notice: Original for SRAM Flattop 12/13-speed chains require a dedicated tooth profile. Please contact us before ordering if Flattop 12/13-speed compatibility is required; customization and an additional fee may apply.

Important Note for Shimano 12-Speed Chains

When using this chainring with a for Shimano 12-speed chain, we recommend replacing the original for Shimano quick link with a KMC 12-speed MissingLink.

For Shimano 9/10/11-speed chains, this change is normally not required.

Decorative Bolt Covers

Optional decorative bolt covers for 1x chainring installation are available separately.

Recommended Tooth Count

The ideal tooth count depends on riding style, terrain, cassette range, and preferred cadence.

Note: This full-cover chainring series is available only from 44T to 60T. Smaller tooth counts such as 38T, 40T, and 42T belong to other STONE chainring models.

Recommendations are for reference only. Please select according to your actual drivetrain ratio and riding conditions.
