The Rotor 3D24 Crankset is based on Rotor's top-of-the-line 3D+ crankset, yet designed for 24mm spindles. Featuring the same CNC-machined 7075 alloy construction, the 3D24 130 is 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.
