A strain-based load cell’s accuracy is degraded by external temperature changes—a problem for cyclists who, as all-weather athletes, expect to be able to use their equipment in all conditions.

Temperature changes cause thermal expansion that can be confused with a load change and result in incorrect power readings, so power meters that use strain gauges must compensate for these errors. Other spider, hub and crank based power meters use algorithms to compensate for these errors.

InfoCrank overcomes these false readings by using the highest-quality strain gauges that are compensated for the thermal expansion of the aluminum crank. Additionally, the use of four strain gauges in each crankset in a full Wheatstone Bridge configuration inherently compensates for temperature, and makes the InfoCrank insensitive to temperature changes. The quality, match, and placement of the strain gauges with the alloy and the full Wheatstone Bridge configuration is the most accurate solution to temperature-corrupted readings.

Every data point from InfoCrank is completely accurate and true, making it the best power for a road bike.
