The XX1 Eagle Power Meter Crankset brings tech over from SRAM's road cycling line and makes it available to the cross-country MTB crowd. The 32-tooth chainring itself features SRAM's X-SYNC 2, which utilizes teeth shaping to maximize chain retention under aggressive shifting and root gardens that have no favorable line options. The aluminum chainring boasts smoother pedaling efficiency and a sort of dental-floss style care, in that it dislikes mud accumulation between the chain links and pushes trail-gunk out with ease. SRAM also includes DUB technology to enhance stiffness and durability, promoting an improved fit between the central drivetrain components, the chainring, crank, spindle, and bottom bracket. Bluetooth and ANT connectivity let us access our ride data quickly and easily.
