AtEscapa, we carry leading drivetrain brands like Rotor. TheRotor INSpider Spider Potentiometer Direct Mount 110x4 fitsperfectly into Rotor’s modular crankset system. With a wide selection of chainrings, cranks, and bottom brackets, it’s ideal for use on everything from mountain bikes to time trial bikes. Technically, the INSpider falls between Rotor’s 2INpower and Inpower power measurement systems. While Inpower measures power on only one crank arm, INSpider determines the power output of both legs using four opposing strain gauges.
This allows for an accurate analysis of pedaling performance and highlights areas for improvement. However, separate analysis of both legs—as is possible with the 2INpower’s independent measurement on both sides—is not available. The system independently compensates for measurement deviations caused by temperature fluctuations. However, the INSpider must be manually calibrated via an ANT+/Bluetooth-compatible bike computer or the Rotor software after installing or changing chainrings and at least once a month. Thanks to fully encapsulated measurement technology, the power meter is insensitive to environmental influences and completely waterproof thanks to a magnetic charging connection. The permanently integrated rechargeable battery guarantees an operating time of up to 200 hours.
Another highlight of the system is the TORQUE 360 analysis feature. The torque curve over one pedal revolution can be analyzed using Rotor’s proprietary software. This measurement technique is particularly valuable for cyclists who use Rotor’s oval Q-Ring chainrings. The software can use the OCA (Optimized Chainring Angle) system to determine the optimal position of the Q-Rings. This allows you to transfer your power to the pedals even more effectively.
