Overfast Aero Carbon Crankset
The Overfast Aero Carbon Crankset is an aero-profile carbon crank arm system designed for riders who want a cleaner, faster-looking drivetrain and a modern fit range. The arms use a direct-mount spider standard (EASTON-compatible), giving you flexibility to build the setup you want—whether that’s a simple crank-and-ring build or a spider-based power meter configuration This listing includes crank arms + spindle only. Spiders, chainrings, and power meters are optional add-ons and are typically purchased separately.
