The SRAM GX Eagle carbon crankset offers consistent performance on every ride. Equipped with the SRAM chainring featuring the X-SYNC 2-tooth profile, the Carbon GX crankset is designed for complete chain control.
The thickness of each tooth is precisely tolerated and controlled to work seamlessly with the inner and outer links of the chain. The DUB technology features a better-designed bottom bracket and a new spindle design.
Together, these allow a more uniform approach to bottom bracket installation, better sealing against contamination, and forward and backward compatibility. Now everyone can benefit from a new level of durability.

Technologies

DUB™

Sram DUB™ technology for bottom bracket and crankset is a tireless workhorse, forward-looking yet backward compatible. It is designed for the most demanding pros and for those who want to use it and forget it exists. DUB™ is compatible with the most important bottom bracket standards and fits any frame without compromise. Additionally, it opens the door to a new type of spindle for the lightest crankset ever produced. A new method that combines the best features of existing GXP and BB30, offering exceptional bearing durability without sacrificing the stiffness of large-diameter spindles.

X-Sync 2

X-Sync 2 Eagle technology is the evolution of the previous X-Sync. The aggressive tooth design ensures better chain retention for a smoother and more efficient pedal stroke. Special attention has been given to the chainring's durability over time; X-Sync Eagle technology reduces friction and the buildup of mud, sand, and dirt on the chainring.

Eagle

Eagle™ represents the latest technology for 1x drivetrains, making them lighter, simpler, stronger, and easier to use. The new line includes completely redesigned components, engineered for superior durability and performance while maintaining a significant weight advantage over other drivetrains. Eagle™ 1x technology also provides an expanded gear range (500% range), comparable to 2x11 drivetrains.

Boost

Boost is the standard wheel and drivetrain specification that opens the opportunity to improve frame geometry with shorter chainstays, wider and stiffer suspension pivots, a wider range of chainring options, as well as more space for larger tires and wider, stiffer wheels.
