R-SPEC eBike Crankset
Meet the 5DEV R-Spec E-Bike Crankset — tuned for modern light and trail e-MTBs. Built brutally stiff, deceptively light, and smarter by design, it delivers lively acceleration with the durability to ride hard, day after day. Precision-CNC’d from 7075 aluminum for elite stiffness-to-weight, the R-Spec eBike crank uses an optimized cutout design to put material where it matters and remove it where it doesn’t. The result is a crisp, responsive pedal feel that holds firm under assist torque without dragging you down with extra grams.
- IS Spline Drive interface designed for use with Bosch, TQ, and new 2025 Specialized LEVO eBike motors
- Steel crank bolt 8mm Hex and billet aluminum self-extractor 16mm hex
