QRC-3S From 348g

Hollow profile, highly stiff, an impressive CNC artwork

QRC2 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 S spider arms feature built-it female chainring-bolts to simplify and enlighten the final assembly We recommend Extralite chainrings for perfect cosmetic match and further weight reduction
