The 3D cranks are the first cranks to have been designed with the input of a pro cycling team together with our Rotor engineers. Drawing on a wealth of technical experience, this innovative product was developed together with Cervelo's engineers, TestTeam riders and the TestTeam's mechanics.
The result is the 3D Crank which is extremely stiff to meet the high demands of Thor Hushovd and the TestTeam's sprinters, yet lightweight enough to satisfy the needs of Carlos Sastre and the climbers on the team.
Rotor utilizes a special manufacturing process, named the Trinity Drilling System. An extruded aluminium 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 aluminium in the core while still maintaining the structural strength of the crank. With this new system Rotor has significantly improved the Hollowminum technology they developed for their Agilis Evo cranks.
