Thanks to the measurement technology integrated into the axle, the Inpower Round Direct Mount R36 Rotor Potentiometer offered by Escapa requires no visible sensors that might detract from the bike’s aesthetics. The system’s weight is also minimal: the Inpower weighs just 560 grams (175 mm, without chainring). The system runs on a standard AA battery, which is hidden inside the axle. The battery can be easily replaced after approximately 300 hours of operation. Data is transmitted via the universal ANT+ protocol.
Power is measured using two pairs of counter-rotating strain gauges on the crank arm, which measure power from the left leg and calculate total power based on that. Another highlight of the system is the TORQUE 360 analysis feature. Using Rotor’s proprietary software, it can be used to analyze the torque curve during a pedaling cycle. This allows you to detect imbalances between the left and right legs or an irregular pedaling stroke. This measurement technology is especially valuable for cyclists who use Rotor’s Q-Ring oval chainrings, as the software can use the OCA (Optimized Chainring Angle) system to determine the optimal position of the Q-Rings based on the torque curve. This allows the cyclist to apply power to the pedals even more effectively.
