Bielas Aldhu Carbon
*Solo se incluyen las bielas. Si también necesitas el eje pedalier, consíguela aquí.
Las bielas Aldhu Carbon de ROTOR son una de las bielas más ligeras del mercado, con un peso final de solo 259 gramos para bielas de 170 mm. Fabricadas en fibra de carbono de alto módulo y compatibles exclusivamente con nuestros ejes de 30 mm, ofrecen un equilibrio excepcional entre ligereza y rigidez. También cuentan con la tecnología 'Twin Leg', que elimina la pérdida de potencia debida al giro del eje al aplicar potencia en cada pedalada.
Además, las bielas Aldhu Carbon ofrecen una amplia variedad de configuraciones para adaptarse a las preferencias y necesidades de cada ciclista. Gracias a nuestra estructura modular innovadora, así como a las diferentes opciones de eje y platos, cada componente está disponible individualmente para adaptarse a la gama actual de usuarios y estándares de ciclismo.


High Modulus carbon fiber made
Unlike conventional carbon crank arms, Aldhu Carbon crank arms are manufactured from high-modulus carbon fibre, produced through a high-temperature graphitization process exceeding 2000 ºC. The result is exceptional stiffness, outstanding dimensional stability and highly efficient power transfer.




30mm Spindle: Stiffer and lighter
Aldhu Carbon crank arms are exclusively available with our 30 mm spindles. This offers a significant advantage, as the spindle is manufactured from 7075-T6 aluminium and its thicker diameter design makes it both lighter and stiffer. As a result, the combination of Aldhu Carbon crank arms and a 30 mm spindle delivers lower weight and greater stiffness compared to traditional 24 mm steel spindles.




Twin Leg Technology®
The patented interface between crank arms and spindle offers a simple assembly but with a firm fit. This design solves a specific problem, which is that power losses are mainly generated by axle torsion under pedaling force. To address this, the robust axle reduces power losses that occur when force is exerted on the left pedal. The balance achieved to minimize these losses is called Twin Leg Technology®.
