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

QRC-3s spider arms feature built-it female chainring-bolts to simplify and enlighten the final assembly

QRC-3 spiders fit standard 5 holes BCD 110mm chainrings and bolts

 

We recommend Extralite chainrings for perfect cosmetic match and further weight reduction

Complete you QRC-3S with Extralite parts: OctaPhase and 1 set of ExtraBolt 1.2S in your favourite anodized finish

QRC3 can be equipped with Aeronose, 3D printed nylon cover, useful to increase aerodynamics and protect from dirt intrusion
