The Shimano STEPS FC-EM900 crank arm set is designed for serious E-bike riders seeking to replace or upgrade their drivetrain components with professional-grade hardware. Utilizing Shimano's proprietary HOLLOWTECH II technology, these arms deliver a high strength-to-weight ratio for improved pedaling efficiency and long-term durability. While this is an elite performance component, users should be aware that it is strictly incompatible with older drive units, including the DU-E8000, DU-E7000, and DU-E6100 systems, making compatibility verification essential before purchase.
