Description
Specifications

Upgrade your mountain biking or gravel riding setup with the Wolf Tooth Elliptical Shimano Chainring 40T, designed for optimal performance, durability, and style. Crafted from high-quality 7075-T6 aluminum, this 40-tooth, 110 BCD asymmetric chainring offers a perfect blend of lightweight engineering and rugged reliability, making it the ideal upgrade for Shimano 4-arm cranksets.

Materials & Construction:

Built from aerospace-grade 7075-T6 aluminum, the Wolf Tooth Elliptical Chainring delivers exceptional strength and longevity while maintaining a lightweight profile. Its durable design ensures it withstands tough riding conditions, mud, and debris, providing consistent performance ride after ride.

Performance & Engineering:

This elliptical chainring features a proprietary 10% ovality with a 112-degree timing after top dead center, enhancing pedaling efficiency by optimizing power transfer during your pedal stroke. The asymmetric 40T design reduces dead spots, increases rear wheel traction, and improves overall power output without sacrificing pedaling comfort or introducing traditional oval ring drawbacks.

Innovative Components & Technology:

Equipped with Wolf Tooth's patent-pending Drop-Stop asymmetrical tooth design, this chainring maximizes chain retention and mud clearance-ideal for muddy trails or technical terrain. Its teeth are engineered for use with 1x9, 1x10, 1x11, and 1x12 drivetrains, offering compatibility with most modern mountain and gravel bike setups. The design also ensures reliable chain engagement and smooth shifting across all compatible chains.

Style & Use Case:

Featuring a sleek black finish, the Wolf Tooth 40T elliptical chainring is as stylish as it is functional. Perfect for mountain biking, gravel adventures, or all-road cycling, it provides improved traction, better power delivery, and enhanced control in varied riding conditions. Whether tackling rugged trails or exploring scenic gravel roads, this chainring elevates your ride.

Key Features:

- Compatible with 4-arm Shimano cranksets (110mm BCD, asymmetric)

- Suitable for 9-, 10-, 11-, and 12-speed drivetrains (except Shimano 12-speed chains without specific Wolf Tooth rings)

- Drop-Stop asymmetrical tooth design for superior chain retention, mud clearance, and wear resistance

- Optimized elliptical ovality for increased rear wheel traction and pedaling efficiency

- Made from durable 7075-T6 aluminum for long-lasting performance
