Rotor 3D Cranks
The Rotor 3D Cranks are created by Rotor, but was tested by the Cervelo Team while partaking in the 2009 Tour de France. When it came to the design, Rotor added their Trinity Drilling System, which is basically three holes drilled into the aluminum bar and runs along the crank. The Rotor 3D Crank road bike set is available in 170mm, 172.5mm and 175mm lengths, followed with 130mm BCD or compact 110mm BCD Spider. You can use with the SAAB bearings or Shimano Hollowtech II bottom bracket. Retail is £245.00 for the set.
