Rotor 3D Steel Axle Crankset 170mm 130 BCD

The Rotor 3D crank was developed by working closely with top professional riders from the Cervelo Test Team. The 3D crank is designed to be stiff enough for the high demands of sprinters and light enough to satisfy the needs of the climbers.

The Rotor 3D crank is made from an extruded aluminum bar and then CNC machined with three internal chambers running the length of the crank. This Trinity Drilling System allows excess aluminum to be removed from the core while still maintaining structural strength. This design is much stiffer and a significant improvement on earlier Rotor cranks. A 24mm steel spindle enhances rigidity and laser-etched graphics give a nice look. The 3D 110mm or 130mm BCD cranks are compatible with any 110mm or 130mm bolt circle diameter chainrings and work with Shimano-compatible external bottom bracket cups.
