STONE aluminium crankset SRAM DUB 8-Bolt

Stone Road & Gravel SRAM DUB 8-Bolt Crankset

The Stone 7050-T7451 aluminum crankset delivers a high-precision alternative to mainstream component standards. Entirely CNC-machined, its architecture is optimized to interface seamlessly with SRAM DUB 28.99 mm spindles and accept direct-mount chainrings, spiders, or power meters utilizing the SRAM 8-bolt mounting standard. The high-stiffness structure ensures maximum power transfer and eliminates mechanical deflection under high torque.

Available in an anodized black or raw aluminum finish, it integrates cleanly into custom builds, free from ostentatious or distracting branding.

Key Features

Fully CNC-machined from a solid block of aeronautical 7050-T7451 aluminum, providing an optimized strength-to-weight ratio.

Spindle architecture fully compatible with the SRAM DUB bottom bracket standard (28.99 mm diameter).

Precision-machined 8-bolt spider interface, compatible with SRAM AXS Direct Mount chainrings, spiders, and power meters (Red, Force, Rival).

Available in an extended range of crank arm lengths from 155 mm to 175 mm to match specific bike-fitting requirements.

Durable surface treatments offered in two low-profile finishes: deep black anodization or brushed raw aluminum.

Compatibility

This crankset is exclusively compatible with bottom brackets designed for the SRAM DUB standard (28.99 mm spindle diameter) across Road, Gravel, and Allroad frames. The drive-side crank interface utilizes the standard SRAM 8-bolt pattern, required for installing SRM or Quarq spiders, AXS power meters, or compatible direct-mount chainrings.
