When it comes to Ekar, which is Campagnolo’s gravel groupset, there are unfortunately not a lot of power meter options. Stages Cycling makes a few Campy power meter crank arms, however they only make versions for Record and Super Record 12-speed cranks and these crank arms won’t fit an Ekar crankset. Likewise, power2max and SRM make some Campagnolo crankset power meters, but these units are ideally suited for 2x road drivetrains.
That leaves power meter pedals. The good news is we have off-road versions from both Garmin and SRM. These power meter pedals use SPD cleats and are available in both dual- and single-sided versions. They will bolt right up to an Ekar crankset and should work great.
