Bringing the goodness of Rotor's premium CNC-machined alloy crankset to bikes that need 24mm spindles, the 3D24 is based on the design of the top-of-the-line 3D+ crank. Enhanced by proprietary Trinity Drilling System (TDS) triple drilling technology to yield perfect stiffness-to-weight ratio. Developed with feedback from top pro cyclists and world champions, ROTOR was able to design a crank that was strong but light, and maintained its stiffness in high-powered sprint finishes.
