Sram GX Carbon Eagle 1x12s boost dub DM 32t X-Sync 2 lunar crankset

The SRAM carbon GX Eagle crankset delivers consistent performance every time out. Featuring SRAM's X-SYNC 2 tooth profile chainring, the Carbon GX crankset is engineered for complete chain control.
Each tooth's thickness is precisely toleranced and controlled to work seamlessly with the chain's inner and outer links. DUB technology features a better-engineered bottom bracket and a new spindle design.
Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of durability.

Technologies

DUB

Sram DUB™ bottom bracket and crankset technology 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 can be mounted on any frame without having to make any compromises. In addition, it opens the door to a new type of axle for the lightest crankset ever produced. A new method that combines the best features of the existing GXP and BB30, offering exceptional bearing life without sacrificing the rigidity of thicker axles.

X-Sync 2

The X-Sync 2 Eagle technology is the evolution of the previous X-Sync. The aggressive design of the teeth ensures better chain retention for smoother and more efficient pedalling. Special attention has been paid to the durability of the chainring, X-Sync Eagle technology reduces friction and the accumulation 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, designed for superior durability and performance, while maintaining a significant weight advantage over other drivetrains. Eagle™ 1x technology also provides an expanded ratio range (500% range), equal to 2x11 drivetrains.

Boost

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