The SRAM Rival E1 DUB Crankarm Assembly is engineered for gravel riders who want a strong, lightweight aluminum crankset. The arms have optimized material placement for an ideal stiffness-to-weight ratio, making it great for any road bike. The arms are available in crank lengths from 160 to 175 mm. The 8-bolt interface works with both power and non-power AXS spiders and integrated chainrings. A DUB bottom bracket system enhances durability and simplifies setup. This version is the standard width but note that there is also a WIDE version available for riders who prefer that configuration.
