Sram Crank GX Eagle Boost 148 DUB 12SP DM X-SYNC 2

Some people push their limits further than others. The GX-Eagle-DUB crankset allows this type of biker to give it their all on every ride. It is the best aluminum crankset we have ever built. Uncompromisingly reliable performance on every ride! With the X-SYNC 2 tooth profile, the chainring ensures perfect chain management. The material thickness of each individual tooth is precisely calibrated to mesh smoothly with the chain links. DUB technology enables a better-sized bottom bracket and a new spindle design. All of this together allows for a coordinated approach to bottom bracket fit, dirt sealing, backward compatibility, and future-proofing. Simply put, the forged GX-Eagle-DUB crankset is the worry-free package for riders who give it their all.
