Compatible with my SRAM AXS power meter?

Yes. The 8-bolt direct mount interface on the back of the Stone crank arms uses the exact standard SRAM 8-bolt pattern. You can directly mount SRAM RED, Force, or Rival AXS power meter spiders, as well as Quarq power meter spiders.

Is this crankset compatible with a Shimano groupset?

Yes. Simply replace your current bottom bracket with a SRAM DUB spindle compatible bottom bracket (28.99 mm diameter) matching your frame's standard (BSA, PressFit BB86, T47, etc.).

Do I need to change my chain to use the Stone Aero chainring?

No. The Narrow-Wide tooth profile is compatible with 10, 11, and 12-speed 1x and multi-speed chains from Shimano and SRAM (including SRAM Flattop and Eagle chains).

Can I change the chainring size later without replacing the crank arms?

Yes. The crank arms use the standard SRAM Direct Mount 8-bolt interface. You can unbolt the chainring via 8 Torx screws to change your tooth count (from 38T to 50T) without removing the spindle from the frame.

What is the gain compared to a stock SRAM Apex/Rival or Shimano GRX 600 crankset?

In addition to full 7075-T651 aluminum CNC machining that eliminates flex found on entry and mid-range cast cranksets, the Direct Mount integration saves approximately 150 to 200 grams while refining the overall look of your drivetrain.

Stone Aero Aluminium SRAM DUB 1x Crankset

Engineered to replace stock Shimano (Tiagra, 105, Ultegra, GRX) or SRAM (Apex, Rival) cranksets, it installs on standard SRAM DUB bottom brackets. Tested and approved by our workshop in Montpellier on CYKL bikes, it ensures direct power transfer without flex during hard accelerations and on rough gravel sections, while providing an aerodynamic gain thanks to its solid aero chainring.

Key Features

7075-T651 CNC machined aluminum: Eliminates deformation under pedaling forces to transfer 100% of your power to the rear wheel.

SRAM DUB 28.99 mm spindle: Guarantees a sealed, play-free fit in standard bottom brackets on the market.

Narrow-Wide tooth profile: Keeps the chain locked onto the chainring without requiring an external chain guide, even on rough terrain.

Direct upgrade alternative: Enables a 1x conversion or replaces a heavy stock groupset without changing the rest of your drivetrain.

Compatibility

Compatible with 10, 11, and 12-speed 1x drivetrains (SRAM Road/Gravel, Shimano Road/Gravel). Installs on any frame equipped with a SRAM DUB compatible bottom bracket (28.99 mm spindle). Direct mount chainring attachment using the SRAM 8-bolt standard.

For installation on a frame equipped with a Shimano setup, simply swap your bottom bracket for a DUB-compatible model. Need advice on choosing crank arm length or chainring tooth count? Contact us.
