STONEDW Direct Mount Single Chainring | AL7075 CNC | For SRAM DUB WIDE Road/Gravel
Powerful Riding Starts with a Perfect Chainring
Engineered from imported AL7075-T651 aluminum with 150HB hardness, this direct-mount narrow-wide single chainring is specifically designed with a 6.5mm offset for SRAM DUB WIDE Road/Gravel cranksets, delivering stiff, precise, and lightweight power transfer.
IMPORTANT: Crank Spindle Compatibility
This chainring’s 6.5mm offset is designed specifically for SRAM DUB WIDE spindle cranksets (Road/Gravel Wide version) — NOT the standard DUB spindle.
Before purchasing, please confirm your crankset is the DUB WIDE version. DUB WIDE cranksets are typically used with wider tire clearance road/gravel frames. Installing on a standard DUB crank may result in incorrect chainline/Q-factor.
Key Features
| Feature | Description |
|---|---|
| Premium Material | Imported AL7075-T651 aluminum, heat-treated & pre-stretched for superior rigidity and minimal deformation |
| Surface Treatment | CNC machined + Anodized finish — corrosion resistant, wear resistant, insulated, fade-proof |
| High Precision | Interface parallelism guaranteed within 0.02mm — same-level accuracy as OEM SRAM chainrings |
| DUB WIDE Offset Design | 6.5mm inward offset, matched to SRAM DUB WIDE |
| Style Options | Cutout (Hollow) — lighter, quieter, less crosswind drag / Closed (Aero) — stiffer, lower flex, ideal for sprint power |
| Color Options | Anodized Black / Silver |
IMPORTANT: Two Tooth Profile Types — Please Choose Correctly
This chainring is available in TWO different tooth profile designs. Please select the correct version based on your chain type:
| Tooth Profile | Chain Compatibility | Marking |
|---|---|---|
| Standard Profile | Non-flat-top chains — compatible with Shimano, KMC, and most 9/10/11/12-speed chains | “9/10/11/12 SP” |
| AXS / Flat-Top Profile | Flat-top chains only — SRAM AXS road chain or SRAM T-Type chain | “FOR AXS 12SP” or “FOR T-TYPE” |
Note: If using the Standard Profile chainring with a Shimano 12-speed chain, please replace the OEM quick-link with a KMC/YBN 12-speed quick-link for full compatibility. 9/10/11-speed chains work directly regardless of brand.
