Some riders test their limits more than others. For these riders, the GX Eagle DUB crankset allows them to go all-in every day they ride. The best aluminum crankset SRAM makes, engineered to deliver consistent performance every ride. Featuring SRAM's X-SYNC 2 tooth profile chainring for complete chain control. Each tooth's thickness is toleranced and controlled to work seamlessly with the chain's inner and outer links. DUB technology’s patented spindle design and bottom bracket provide a uniform approach to fitment, better sealing, and forward and backward compatibility. Simply put, the forged aluminum GX Eagle DUB crankset is the no-frills choice of riders who know.
