ROTOR INSPIDER ALDHU CARBON CRANKSET ROAD This is Rotor lightest road crankset with powermeter, 650g with 170mm crankarms and 50/34 round chainrings. The INspider power meter offers very high accuracy, with combined power measurement of both legs allowing you to monitor your progression during every ride. ALDHU Carbon cranks incorporate Twin Leg-technology, which eliminates power losses caused by spindle torsion. This will give you the best stiffness/weight ratio on the market.  ROTOR chainrings are compatible with Shimano® 11- and 12-speed groups and have an aerodynamic design that improves airflow. The optimised sprocket set allows you to shift accurately in any situation. The new architecture improves structural rigidity, making them very popular with demanding cyclists. If health and performance are important to you, we recommend the Q RINGS oval chainrings. These allow you to pedal more efficiently, maximising the power on the pedals. The load on your knees is also reduced, allowing you to pedal more healthily.
