Rival Crankarm Assembly delivers lightweight alloy strength with AXS-ready design
What Our Gearhead® Experts Are Saying:
"The Rival crank arms punch way above their weight. They're impressively stiff for aluminum, and I love that they’re ready for power integration with SRAM’s 8-bolt system. Whether I’m building up a road or gravel bike, this crank is an easy choice for clean performance and future upgrades."
We don’t always need carbon to go fast. The SRAM Rival Crankarm Assembly takes a smart, efficient approach to alloy performance, engineering stiffness and strength right where we need it. Built from lightweight aluminum and designed with strategic shaping, these arms deliver excellent power transfer without dragging down your build.
Whether we’re riding road, gravel, or a little of both, the 8-bolt interface gives us full flexibility to run power or non-power AXS spiders and integrated chainrings. With lengths from 160mm to 175mm and compatibility across standard and WIDE DUB bottom brackets, Rival makes getting the right fit easy while keeping things clean, durable, and future-proof.
