QRC-3 From 358g

Hollow profile, highly stiff, an impressive CNC artwork QRC3 spiders fit standard 5 holes BCD 110mm chainrings and bolts, double and single chainring setups

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 can be equipped with Aeronose, 3D printed nylon cover, useful to increase aerodynamics and protect from dirt intrusion QRC-3 are supplied with BB bearings and cups that fit every common frame-standard QRC3 cranks come complete with the BB assembly, no other parts are required to install them on your frame
