The Fulcrum E-Metal 3 Boost 29" wheels are designed for trail and enduro riding. These specific electric MTB wheels guarantee stability and manoeuvrability. The E-Metal 3s respond quickly to stress thanks to the record stiffness of the hub-and-spoke rim assembly, which guarantees the transmission speed of handlebar and pedal controls to the ground. This is made possible by a wheel specially designed for the front, higher and directional, and a wheel for the rear, reinforced by the "In-frame" and ready to guarantee maximum power transmission.TechnologiesAsymmetric Rim to improve rim tension by balancing forces from brakes and cassette2-Way Fit Ready converts your inner tube wheel to tubeless Easy.
