Successful Giro Debut of Rotor 3D Cranks

Cervélo TestTeam riders have been using the new 3D Cranks from Rotor Bike Components, successfully during the 2009 Giro d’Italia. “The 3D cranks are the first cranks to have been designed with the input of a pro cycling team together with our Rotor engineers,” says Ignacio Estellés, President Rotor Bike Components. ”Drawing on a wealth of technical experience, this innovative product was developed together with Cervélo’s engineers, Test-Team riders and the Test-Team’s mechanic staff.”

“We have a four step protocol for product development with the Test-Team,” explains Damon Rinard, Cervélo Test-Team Race Engineer. “A partner, in this case, Rotor develops and tests the proposed new product. We then review it and check the in-house data, testing it in different riding situations. Then the Cervélo Test-Team mechanics install it and the riders try it in training; both provide us with their feedback. Once it’s been approved at these three levels, the product is then available for the fourth level: use in races.”

The result is the 3D Crank which is extremely stiff to meet the high demands of Thor Hushovd and the Test-Team’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.
