SX Eagle DUB Crankset

DUB stands for Durable Unified Bottom Bracket, a standard developed by SRAM that integrates the crankset and bottom bracket into a single, more durable design. This system enhances the performance and longevity of your bike's drivetrain by ensuring better alignment and reducing friction, which means smoother rides and less maintenance over time.

Eagle Technology is a proprietary system by SRAM that offers a wider gear range, lighter weight, and improved durability for mountain bike drivetrains. This technology allows you to tackle various terrains more efficiently, making it easier to climb steep hills or navigate rough trails, ultimately enhancing your overall riding experience.

X-Sync2 is a specialized tooth design used on SRAM chainrings that features taller and narrower teeth. This design helps keep the chain securely in place, improving chain retention and minimizing the risk of the chain dropping off during rides. It's particularly beneficial for off-road biking, where rough terrain can lead to chain issues.

The chainline refers to the alignment of the chain with the chainring and rear sprockets. A proper chainline ensures smooth and efficient chain movement, reducing wear and improving shifting performance. A 49mm chainline is specifically designed for certain rear axle spacings, optimizing how your bike's drivetrain components interact for better performance.

Bolt Circle Diameter (BCD) is the diameter of the circle that passes through the center of the chainring bolts. It is crucial for ensuring compatibility between your crankset and chainrings. A direct mount BCD means the chainring attaches directly to the crank arm, simplifying installation and maintenance, which is especially helpful for those who prefer a hassle-free setup.

Technologies like DUB, Eagle, X-Sync2, and optimized chainline work together to improve your bike's efficiency, durability, and shifting performance. By reducing friction, enhancing gear range, and ensuring proper chain retention, these innovations allow for smoother rides, better handling on various terrains, and less frequent maintenance, making your biking experience more enjoyable and reliable.
