e*thirteen e*spec Race Carbon Crank Arm

No, these are specifically engineered for compatibility with Brose S Mag and Fazua Ride 50 motor systems. Please verify your motor model before purchasing to ensure a proper fit.

These arms feature reinforced front and rear faces specifically designed to handle the high-impact environment of e-mountain biking. While carbon is lighter, this construction ensures they are robust enough to withstand trail debris and strikes.

The integrated self-extractor simplifies maintenance by allowing you to remove the crank arms using only an 8mm hex wrench. It eliminates the need for a separate crank puller tool, making field repairs or service much faster.

No, the set includes a protective vinyl cover designed to shield the carbon surface from scuffs and wear. It helps maintain the finish and aesthetic of the arms over time.

A 165mm length is a standard choice for e-MTBs because it provides better ground clearance, reducing the likelihood of pedal strikes on technical terrain. It also promotes a more efficient pedaling cadence for electric assist systems.
