Rival E1 Crank Arm Assembly delivers efficient stiffness with upgrade-ready compatibility
What Our Gearhead® Experts Are Saying:
"These Rival E1 arms are deceptively good—aluminum done right. They’ve taken the best cues from higher-tier builds but made it more accessible and just as capable. I run them with a Wide DUB BB on my gravel bike and they’ve been solid through everything."
From pavement to gravel, the Rival E1 Crank Arm Assembly is your foundation for a modern drivetrain—durable, versatile, and ready for future upgrades.
