brought the SSP (Stress Split Profile) concept to the
extreme
QRC3 are
a whole step forward: 17% lighter and 15%stiffer
Hours of state-of-art, point-to-point 5 Axis 3D milling technology are employed on each unit
Each crankset receives the same sculpturing process and care once limited only to works prototypes
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
Self extracting left crank: no special tools required
Stylish and precise "click-dial" bearing preload system
QRC3 spiders fit standard 5 holes BCD 110mm chainrings and bolts, double and single chainring setups
