Rival Crankarm Assembly delivers efficient alloy performance and future-ready compatibility
What Our Gearhead® Experts Are Saying:
"For an alloy crank, the Rival arms are really impressive. They feel solid under power and still keep the weight in check. Plus, with the 8-bolt setup, I can easily add a power meter later or run integrated rings depending on my build. It’s a great choice if you want performance without going full carbon."
Designed for riders who want durability and performance without the high cost of carbon, the SRAM Rival Crankarm Assembly blends precision-forged aluminum with SRAM’s forward-thinking AXS ecosystem. The arms are engineered to remove excess material and concentrate strength where it matters, giving us a responsive pedal stroke that doesn't flex under pressure.
Its 8-bolt interface provides direct compatibility with SRAM power and non-power spiders and integrated chainrings, making it a versatile hub for any 12- or 13-speed build. Thanks to the DUB spindle and broad bottom bracket compatibility, we can use these crankarms across a wide range of road and gravel frames—standard or WIDE. Whether we’re building up a new bike or upgrading a drivetrain, Rival gives us modern performance, fit flexibility, and upgrade-ready reliability.
