ROTOR utilizes a special manufacturing process, named the “Trinity Drilling System. 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. Comes together with original bottom bracket and chainring.
