Rotor 3D Crankset w/ Steel Spindle
Rotor developed the 3D crank to be extremely stiff in order to meet the demands of Thor Hushovd and the sprinters of the Cervelo Test Team. But it also needed to be lightweight enough to satisfy the needs of Carlos Sastre and the climbers as well. Rotor utilizes a special manufacturing process — the Trinity Drilling System. In this process an extruded aluminum bar is intricately CNC machined with three drilled holes through the length of the crank. The result is a unique triple hollow crank arm that enables Rotor's engineers to remove the excess aluminum in the core while still maintaining the structural strength of the crank.
