The 2INpower SL and INpower V3 are both crank based power meters, with the difference being that the 2INpower SL is dual-sided and rechargeable, whereas the INpower is single-sided and powered by a AA battery. The 2INpower SL is a power meter with strain gauges in both the crank arm and spindle for precise, independent measurements.
The INspider, on the other hand, is a spider-based power meter, where the strain gauges are in the spider itself. The INspider is compatible with all of our current model cranks, including the ALDHU and VEGAST.
