5DEV R-SPEC Specialized Brose eCranks

5DEV R-SPEC Specialized Brose eCranks Info

5DEV R-SPEC Specialized Brose eCranks are purpose-built for aggressive e-MTB riders running early-generation Specialized Levo and Kenevo platforms with Brose motors. Machined with 5DEV’s exclusive crank profile, these cranks are designed to reduce crank strikes when climbing through technical, rock-heavy terrain—helping you keep momentum where it matters most.

Each crank is CNC-machined from 7075-T651 aerospace-grade aluminum billet for exceptional stiffness and impact resistance under high torque loads. The refined arm shape improves ground clearance without compromising strength, making these cranks a confident upgrade for riders who push their e-bikes into demanding terrain.

A 182mm Q-factor (when installed on Specialized Levo/Kenevo) provides stability and control, while 155mm and 160mm length options allow riders to fine-tune pedal clearance and fit. The IS spline drive interface ensures a solid connection to compatible Brose motors. Installation is quick and service-friendly thanks to a robust 8mm alloy steel crank bolt and an integrated billet aluminum self-extractor.

Important Compatibility Note: These cranks are not compatible with Specialized SL eBikes or the 2025 Specialized Levo.
