R-spec Ebike Crankset - 7075-T651 Aerospace Aluminum

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.
