SRAM GX ALUMINUM EAGLE 12S BOOST DUB

Some riders push their limits more than others. For these riders, the GX Eagle DUB crankset allows them to go all in every day they ride. It's the best aluminum crankset we make, designed to deliver consistent performance on every ride.

Featuring our X-SYNC 2-tooth profile for complete chain control. The thickness of each tooth is tolerated and controlled to work seamlessly with the inner and outer chain links.

The patented spindle and bottom bracket design of DUB technology provides a consistent approach to mounting, improved sealing, and forward and backward compatibility. Simply put, the forged aluminum GX Eagle DUB crankset is the no-nonsense choice for riders who know.

DUB™

Sram DUB™ bottom bracket and crankset technology is a tireless "workhorse", projected into the future but at the same time 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 compromise. In addition, it opens the door to a new type of axle for the lightest crankset ever produced. A new method that brings together the best features of existing GXP and BB30, offering exceptional bearing durability without sacrificing the stiffness of thick 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 smoother and more efficient pedaling. Particular 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 and makes them lighter, simpler, more durable, 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), equivalent to 2x11 drivetrains.
