With the R-Volver hubs the Spaniards from the house ROTOR present their first hub row. The pioneers in the field of oval chainrings in cycling are also an innovative and independent way of life and the appearance of the R-Volver hubs. For example, a patented, almost contact-free system is used, which is a mixture of toothed disc freewheel and pawl freewheel.
When rolling, the specially shaped toothed disc with bevelled teeth is pushed away from the 6 bolts and the freewheel runs with extremely low resistance. This significantly reduces the friction resistance to the other system and the wheel rotates longer. At the smallest pedal movement the bolts shoot into the toothed disc and ensure a direct force closure. The system is geared over 25 teeth and thus rests every 14.4 degrees with a pedal revolution. Because no fixed connection between toothed disc and hub body is necessary, the system saves weight against other freewheel systems.
The hub bodies are CNC machined to 100%. Contact-reduced bearing gaskets not only ensure a long service life but also reduce the friction resistance of the hubs when rolling. The milled hub flanges for J-Bend spokes reduce the weight and give the R-volver hubs their special look.
