The SRAM Red 1x XPLR E1 DUB Wide Crank Arm Assembly takes the lightest and stiffest crankarms in the lineup and makes them even lighter. By refining the hollow carbon construction, SRAM reduced the weight by 29 grams compared to the previous generation. The crankarms feature an 8-bolt interface compatible with both power and non-power AXS spiders and integrated chainrings. With the addition of a 160mm crankarm length option, it caters to more rider preferences. The DUB bottom bracket ensures durability and simplicity, making this assembly both high-performance and versatile.
