Technology:

Aluminium CNC
Computer Numerical Control (CNC) milling ensures a precise and uniform production process. This is particularly important when manufacturing components that must function properly and work in congruity with other parts. Thanks to state-of-the-art CNC equipment, Rotor parts are manufactured with extreme precision, down to a hundredth of a millimetre.

Oval Chainrings
Bio-mechanical studies show that Q-Rings provide better performance than conventional chainrings. The effect is achieved by making the largest muscle groups in the legs more effective and eliminating the dead centre when pedalling. This results in a much smoother and rounder ride overall, with less muscle fatigue. The biggest advantages of using Q-Rings are the significant improvement in general fitness due to improved pedalling, greater sprinting ability due to the elimination of dead centre, slower muscle fatigue, and ultimately an increase in cardiovascular endurance for athletes.
