Both crank-arms are "sculptured" with a sophisticate 3D cnc process for a higher freedom in multi-dimensional shaping
CNC artwork combines lightness with elegance
2 years of accurate FEA simulations and dozens of different prototipes destroyed to achieve an incredible level of safety
Special custom tools have been developed to achieve a super deep and efficient hollow structure
