Rotor 3D 30MM 172.5 52/36 110BCD CRANK SET

The 3D30 Crankset's design is based on our top-of-the-line 3D+ crank, and is enhanced by our proprietary Trinity Drilling System (TDS) triple drilling technology to yield perfect stiffness-to-weight ratio. Unlike other ROTOR cranksets, this crank is equipped with a 30-millimeter spindle, ideal for those who covet stiff power. It was developed in conjunction with top pro cyclists and world champions for its featherweight feel with stiffness that keeps you in control when you're sprinting through the last meters, pushing for your spot on the podium.
