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 & controlled to work seamlessly with the chain's inner & outer links. DUB technology features a better-engineered bottom bracket & a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination & forward & backward compatibility. Now everyone can benefit from a new measure of durability.
