No twisting, no warping, just pure energy transfer. 7055 cold forged aluminum crank arms are drilled lengthwise to create a trellised structure that gives unparalleled stiffness-to-weight ratio. The stiffness means that each pedal stroke delivers more power and energy into your tires, saving you energy on your next big climb. Built with Rotor’s universal bottom bracket 30mm axle, these cranks are compatible with almost every bottom bracket available.
