Engineered from imported AL7075-T651 aircraft-grade aluminum with a hardness of 150HB, the STONEDW SR3-6OF direct mount chainring delivers superior strength, stiffness, and durability for serious riders who demand reliable chain retention and efficient power transfer.

Key Features

- Closed/Solid Design (YF) – Enhanced stiffness, reduced flex under high torque – built for power output
Precision Engineering: Interface parallelism guaranteed within 0.02mm for smooth, wobble-free rotation
Reinforced Tooth Profile: Thickened outer edge design increases rigidity and minimizes lateral deflection
6mm Inboard Offset: Chainline = 49mm, compatible with standard SRAM DUB/GXP spindle cranksets
3-Bolt Direct Mount Interface: Single, foolproof installation orientation
Thickness: 9.6mm
