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 we make, engineered to deliver consistent performance every ride. Featuring our 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 provides 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.
