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

• 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, and 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 
• Two Style Options:
  • Cutout (Hollow) Style — Lighter weight, lower chain noise, less crosswind interference, ideal for lightweight builds
  • Closed (Aero) Style — Higher stiffness, lower flex, ideal for high-power sprint riders
• Two 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:

⚠️ 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.
