Lewis ALU MTB Aluminum Chainring

Upgrade your drivetrain with the precision-engineered Lewis ALU MTB Chainrings, crafted to stand up to aggressive riding styles. Machined from high-strength 7075 aluminum, each ring features a hard-anodized coating that is three times harder than standard anodizing, ensuring exceptional resistance to wear and long-lasting durability.

Available in both SRAM 3‑bolt and 8‑bolt configurations, these chainrings come in several sizes and offsets to match your setup:

• 3‑Bolt: 30T (3 mm offset), 34T (3 mm offset)

• 8‑Bolt: 34T (3 mm or 6 mm offset)
   

The lightweight hollow-support design reduces unsprung mass while maintaining structural strength, ideal for high-intensity pedaling and technical terrain.

Features & Benefits

• Extreme wear resistance: A self-developed diamond-hard anodizing finish for style and durability.

• Optimized tooth profile: Positive & negative tooth shaping enhance chain retention and smooth shifting.

• Bolt compatibility: Choose 3‑bolt for SRAM direct-mount cranksets or 8‑bolt for wider compatibility.

• Weight-saving design: Hollow 3D lattice architecture keeps things light without sacrificing strength.
