SRAM GX DUB crankset in the Eagle carbon version. The carbon version uses a proprietary carbon layup. 28.99mm DUB spindle standard.

This crankset came with my Top Fuel 9.9. It has always had end protectors and frame protection tape from when they were new. Only 646 trail miles. No issues. $325 list price. Spindle adjuster ring is included.

I also have a compatible newer 34t chainring listed separately - see 105mi. SRAM X-Sync 2 Eagle Direct Mount Chainring 34T - $65.

SRAM GX Carbon DUB: Features carbon arms with a "Lunar" color option, designed to be lighter than the aluminum version.
Compatibility: fully compatible with 1x12 speed SRAM Eagle drivetrains.

The SRAM carbon GX Eagle crankset delivers consistent performance every time out. 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.
