SRAM Red Crank Arm Assembly

Elite-level crank arms engineered for road performance.

These premium SRAM Red crank arms are designed for cyclists seeking the lightest, stiffest, and most responsive drivetrain performance — ideal for racing, road training, and high-end builds. Built with advanced carbon construction and optimized for modern drivetrains, they offer a precision upgrade that enhances power transfer and reduces rotational weight.

Key Features

• Ultra-Light Carbon Construction: Hollow carbon arms are optimized to shed weight while maintaining exceptional stiffness for efficient power transfer.
• DUB Spindle Compatibility: Uses SRAM’s DUB bottom bracket standard for broad compatibility and simplified installation.
• 8-Bolt Interface: Designed to mate with AXS spiders — power or non-power — and supports direct-mount chainrings (sold separately).
• Multiple Lengths Available: Offered in a range of crank arm lengths (160 mm to 175 mm) so you can fine-tune fit and pedaling dynamics.
• Road-Optimized Performance: Perfect for 12-speed road drivetrains and compatible with SRAM RED components and systems.

Why It’s Great

These crank arms deliver top-tier responsiveness and weight savings for riders who demand performance and precision. The carbon build keeps the assembly feather-light while the direct-mount interface simplifies your setup with modern road drivetrains. Whether you’re racing, training, or building an elite road bike, these arms are a high-impact upgrade.
