Lewis ALU MTB Aluminum Chainring

Lewis ALU MTB Chainring

Lightweight 7075 aluminum chainrings built for strength, wear resistance, and confident chain retention on aggressive MTB setups.

The Lewis ALU MTB Chainring is designed for riders who want a durable, lightweight direct-mount chainring that can handle aggressive trail and mountain bike use. Precision-machined from 7075 aluminum, each chainring is finished with a specialized hard-anodized coating designed to improve wear resistance and long-term durability. The result is a performance-focused MTB chainring built to maintain tooth integrity, resist abrasion, and perform reliably in demanding riding conditions.

Available in both SRAM 3-bolt and 8-bolt mounting options, the Lewis ALU MTB Chainring is offered in multiple tooth counts and offsets to help riders match the chainring to their crankset and drivetrain layout. Its lightweight hollow-support design helps reduce weight while maintaining the stiffness needed for technical terrain, strong pedaling loads, and hard trail use.

Available Options

• 3-Bolt: 30T (3 mm offset), 34T (3 mm offset)
• 8-Bolt: 34T (3 mm offset or 6 mm offset)

Features & Benefits

• 7075 Aluminum Construction: High-strength aluminum provides an excellent balance of stiffness, durability, and low weight for aggressive MTB use.
• Enhanced Hard-Anodized Finish: Wear-resistant coating is designed to improve surface durability and help extend chainring life in harsh riding conditions.
• Optimized Tooth Profile: Positive and negative tooth shaping is engineered to improve chain retention and promote smoother running over rough terrain.
• Direct-Mount Compatibility Options: Available in SRAM 3-bolt and 8-bolt configurations to suit different crank and drivetrain setups.
• Weight-Saving Hollow Design: Internal support structure reduces unnecessary mass while preserving chainring strength.
• Built for Technical Riding: Designed to handle high pedaling loads, rough terrain, and aggressive mountain bike riding styles.

Why Chainring Design Matters

A quality mountain bike chainring affects more than just gearing. Tooth profile, material quality, offset, and surface hardness all influence chain retention, drivetrain wear, and long-term performance. The Lewis ALU MTB Chainring is built to provide better durability and dependable chain control for riders who push their bikes hard on trail, enduro, and technical terrain.
