The Sram GX Eagle FAT5 crankset is an excellent choice for every fat tire bike enthusiast. Made from durable 7000 series aluminum that has been cold forged, it is ideal for mountain trails where equipment durability is crucial. The chainring, which is built with X-Sync 2 technology, securely holds the chain, preventing it from dropping, while the 28.99mm diameter DUB axle offers high stiffness. The chainline and axle length are specially adapted for Fatbike frames.

The main technologies include:

• X-Sync – Each tooth on the chainring is designed with a specific shape and thickness, ensuring perfect chain compatibility for smooth operation and proactive chain drop prevention. Benefits include increased chainring lifespan and quiet drivetrain operation.
• DUB – A modern crank axle standard with a 28.99mm diameter that offers greater stiffness and simplicity. It is compatible with any frame using the appropriate bottom bracket.
• Direct Mount – The crankset chainring features a direct mount system, making chainring changes easier.
• Eagle – A 12-speed drivetrain technology offering a wide range of gears and perfect component integration. It delivers top performance thanks to careful mechanical engineering.
