ROTOR crank IN Power REX 1.2 XC2 MTB LK110 / 60
The Spanish component manufacturers rotor provides the IN Power probably the most discreet performance measurement system on the market. The integrated into the crankshaft measuring technique there is no visible, the appearance of the wheel from interfering sensors. Also the weight of the system is minimalist. So the IN Power version of Rex crank brings only 50 grams more weight to Version without power indicator on the scale. The system is fed by a standard AA battery, hiding behind a rotatable sealed cap to the crankshaft. Thus, the battery can be replaced after a period of about 300 hours without any issues with a handle. The data is transferred by means of universal ANT + protocol.
Another highlight of the system is the TORQUE 360 evaluation option. Using rotor house software can about them, the torque curve during a pedal rotation analyze. So weaknesses between left and right leg or a non-circular passage can be detected. Especially valuable this measurement technique is used for driver's rotor oval Q-Ring chainrings. The software can determine the optimum position of the Q-Rings on the torque curve over the OCA (optimized-chainring-angle) system. So the driver can bring his power even more effective on the pedal. With the proven 30 mm UBB crankshaft the system in conjunction with rotor UBB bottom bracket with all major bearing standards compatible (except BB90 / 95).
