What Our Gearhead Experts Are Saying:

"I run the Rival E1 crank arms on my all-road setup, and they’ve been flawless. The stiffness is impressive for an aluminum arm, and I love that I can add a power meter later with the 8-bolt interface. It's all about smart simplicity."

We rely on our cranks to channel every ounce of effort into forward motion, and the Rival E1 Crank Arm Assembly delivers. Engineered with precision-forged aluminum, these crank arms maintain the ideal balance of stiffness and weight, putting strength where it matters most and shaving grams where it doesn’t. Whether you're training, commuting, or just out for long days on the road, these arms ensure smooth, efficient power delivery every time you turn the pedals.

The 8-bolt direct mount interface is compatible with both power and non-power AXS spiders and integrated chainrings, letting you upgrade your ride over time. Available in a full range of lengths, it fits nearly any rider and frame. It’s the foundation for a drivetrain that can grow with your ambitions.
