Description
Specifications

Upgrade your MTB drivetrain with the Easton Chainring 40T Direct Mount CINCH - a high-performance, lightweight, and versatile component designed for aggressive trail riding, cross-country, gravel, and mountain biking. Crafted from durable aluminum, this 40-tooth round chainring offers exceptional strength and precision engineering to enhance your bike's efficiency and reliability over rough terrains.

Materials & Construction:

Made from high-grade aluminum, the Easton CINCH chainring balances lightweight performance with durability. The material's excellent strength-to-weight ratio ensures long-lasting wear, even during demanding rides.

Performance & Engineering:

Designed with a narrow/wide tooth profile and tall, direction-specific teeth, this chainring provides superior chain retention, reducing the risk of chain drops on rugged trails. The optimized tooth geometry facilitates positive chain roller engagement, crucial for maintaining smooth power transfer and stability across uneven terrain. The innovative tooth design also minimizes running noise at the extremes of the cassette and offers excellent mud-shedding capabilities, making it ideal for muddy, off-road adventures.

Components & Technology:

The direct mount CINCH system simplifies setup and enhances weight savings, allowing quick and secure chainring swaps without additional tools. The variable tooth width further improves chain engagement and retention for a confident ride. Compatible with 10, 11, and 12-speed drivetrains-including Shimano, SRAM Eagle, and Campagnolo-this chainring ensures seamless integration with your existing setup.

Style & Use Case:

Featuring a sleek black finish, the Easton CINCH 40T chainring complements various mountain bike and gravel bike aesthetics. Its versatile 47mm chainline and compatibility with Easton 129mm spindle optimize performance on standard 135/142mm rear hub spacing, making it suitable for cross-country, trail, gravel, and cyclocross applications.

Innovative Features:

- Lightweight at just 91 grams for optimal weight savings

- Narrow/wide tooth profile for enhanced chain security on rough terrain

- Optimized for 11-speed systems, with compatibility across 9, 10, and 12-speed drivetrains

- Easy-to-install direct mount CINCH interface for quick swaps and maintenance

- Mud-shedding and reduced noise capabilities for cleaner operation in variable conditions

Elevate your mountain biking and gravel riding experience with the Easton Chainring 40T CINCH - a precision-engineered component designed for durability, performance, and versatility. Whether tackling technical trails or racing cross-country, this chainring offers the reliability and efficiency you need to push your limits.

  • Lightweight 40T aluminum direct mount CINCH chainring designed for MTB, gravel, and cyclocross, offering a durable yet weight-efficient construction at just 91g for enhanced performance on rugged terrains.
  • Engineered with a narrow/wide tooth profile featuring tall, directional teeth to ensure exceptional chain retention and secure engagement over rough and muddy conditions.
