The 4iiii PRECISION PRO Shimano DURA-ACE 9200 Dual-Sided Power Meter combines 4iiii’s dual-sided power sensors with Shimano’s top-end DURA-ACE 9200 crankset. The result is an accurate, stiff, lightweight power meter that measures power from both legs. In addition, with a power sensor located separately on both crank arms, the power meter can measure forces generated by each leg individually.
